Introducing a new generation of servo valves that deliver exceptional performance and precision, without compromise to cost, efficiency, and industrial reliability.
Two-stage servo valves, or mechanical feedback valves, are valued for their compact size and excellent dynamic performance, including fast response times and high-frequency capabilities. However, they come with limitations. The small orifices and high-pressure seals that help maintain performance can also make them more susceptible to contamination and blockages, especially if operated in harsh environments. Additionally, because they lack onboard electronics, they do not deliver the same level of repeatability and accuracy as modern direct drive valves.
Direct Drive Valves
Direct drive valves utilize an electrical feedback design. Contamination and hysteresis occur less frequently with direct drive valves making them more durable for demanding industrial applications. However, this comes with trade-offs in performance and size. Direct drive valves are generally heavier and bulkier in design, with slower step and frequency responses compared to two-step valves. This makes them less suitable for high-performance applications where dynamic response is critical.
Domin Valves
A Domin valve is a considered a servo proportional valve, a hybrid between two-stage servo valves and direct drive valves. Domin merges the benefits, such as the performance, efficiency, precision, and compact size from both without needing to compromise. Domin’s S6 Pro, for instance, offers an unmatched balance of performance and efficiency, boasting a 78% lighter design, a 67% faster response, 340% higher bandwidth, and 73% higher maximum flow compared to an equivalent direct drive valve.

Check valves block an oil flow in one direction and allow it in the other direction. They are a type of shutoff valve. The check valve is inserted when an oil flow shall be allowed in one direction only. Meanwhile, the usage of check valves prevents backflow of the fluid.
Advantages at a Glance:
Spherical shell
Available as screw-in or caged version
Nominal size 1/16 – 1/8 – 1/4 – 3/8 – 1/2 – 3/4
Working pressure 10,000 psi
BSP or metric thread
The HYTORC-check valves are available with a screw-in or caged design. Even so, both designs can be obtained in two flow directions: with the screw-in direction closed or with free-flow. The spherical cap remains reliably tight in every position, in case of multiple switching cycles and under severe stress.
The HYTORC check valve easily screws into a regular hole (Dimensions screw-in drill). The screw-in check valves are sealed through an edge sealing which is turned to the cage. The edge sealing, together with the drill draft, forms a gap-free chamber for the O-Ring. The gap-free chamber and the O-Ring are repeatable sealing.
The valve is made of a high-strength hardened steel. Moreover, the ball seat is specially treated and the spherical shell is manufactured with a high tensile hardened and polished ball bearing ball. Thus, the design of the check valves is compact and economical which saves space and offers simple installation.

Comparing Size: Butterfly Valve versus Ball Valve on 4″ Pipe
For a 4″ pipe, butterfly valves are nearly 77% shorter and 71% lighter than a ball valve of the same diameter.
Ultra-compact profile to minimize space requirement:
In applications where fitting ball valves into the design poses a challenge, butterfly valves provide an effective solution. These valves are significantly shorter and lighter than their counterparts, facilitating easier handling and installation. The advantages of this design become increasingly evident as the nominal diameter rises. This is particularly beneficial in mobile hydraulics where space is a premium.
Convenient, simplified maintenance:
Thanks to internal clamping bolts, the valve is tightly secured to the reservoir even when even when disconnecting pipes or flexible connectors. This design enables maintenance without draining the reservoir.
Easy installation:
Shut off valves can be fitted between flanges due to the lateral recesses. Alternatively, heavy suction pipes can be held with additional screws.
No loss of oil volume:
The valve’s inner diameter is larger than the pipe, enabling full flow capacity without compromising on oil volume. This feature is crucial for maintaining efficient and precise control.
Automatic locking mechanism:
The self-engaging lock bar provides a secure and stable connection. The lock bar automatically engages in all switch positions; fully open, closed, or at an intermediate position, and ensures arresting of the valve’s position even without a shift lever.
Limit switch for preventative measures:
Prevent damage to your pump by making sure the valve is open prior to turning on the pump.

Selecting the correct valve actuator will increase performance, uptime, reliability, and safety while reducing maintenance costs. Although the most common and important use of an valve actuator is to open and close valves, current actuator designs go far beyond the basic open and close function. The valve actuator can be packaged together with position sensing equipment, torque sensing, motor protection, logic control and digital communication capacity all in a compact, protected enclosure. Applications include: power plants, oil and gas, industrial, ships and chemical industries. Below is a listing of valve actuators available from IC-Fluid Power.
Reciprocating or single-stroke cylinder intensifiers are used to increase the pressure output of an existing low-pressure system, giving a boost of pressure when and where it’s needed, yielding greater pressure.
How are Pressure Intensifiers Used?
Pressure intensifiers are powered by a pump, which is operating at a set pressure. The hydraulic intensifier consistently delivers flow until the output pressure has been reached. The flow from the pump enters the intensifier, where two pistons of different sizes (respective to the intensification ratio) pump the fluid, thereby intensifying it. In the process, waste flow is returned to the tank.
Pressure Intensifier Benefits
Boost pressure from existing equipment
Avoid costly investments in machinery, such as an HPU or pump
Save space due to the intensifier’s simple, compact design
Use with standard industry pipe clamp
Choose from a large range of mounting options (in-line, flange-on, CETOP, etc.)
Increase energy savings and reduce carbon footprint
A hydraulic pressure intensifier can be used for many applications. These include rupture tests on hoses, pipes, and containers; hydroforming; bolt tensioning; presses; and proportioning precisely defined volumes. It is also useful for demolition tools, such as stone crushing tools and hydraulic construction tools. Additionally, it can be employed in hydraulic power packs and workholding cylinders.
Mobile Applications
In mobile applications, such as cranes, pressure intensifiers increase the pressure in the cylinders during retraction and ensure sufficient pressure within the stabilizer. The outlet pressures for this application include 3625 psi/250bar – 4350 psi/300 bar.
Pressure Testing
Pressure intensifiers can be used to provide test pressures for hydraulic components at 7250 psi/500 bar – 11,600 psi/800 bar, and for tubes and hoses for diesel engines (2,000+ bar). Pressure can be boosted from existing HPUs to negate having to buy an additional test pump.
Hydraulic Tools
Power hydraulic tools with a pressure intensifier connected to an existing power source. Intensifiers can boost pump pressure from as low as 1,450 psi/100 bar to an operational range of 4,350 psi/300 bar – 11,600 psi/800 bar.
No, pressure intensifiers are solely designed to intensify pressure.
Pressure intensifiers sacrifice flow for increased pressure and should not be used when needing simultaneously high flow and high-pressure outputs
Yes.
You can use water glycol with an intensifier, but the glycol concentration must be greater than 5%. For anything under 5%, a stainless-steel intensifier is required. Pressure intensifiers can be used with other fluids requiring special sealing. There are multiple sealing options, such as EPDM, Viton, etc. that can be selected for fluid compatibility.
Intensifiers are characterized by the desired pressure, inlet flow, and mounting style.
Selection is based on the maximum low pressure they can handle, along with any additional features specified by the application requirements. Follow our easy flow chart to see which intensifier you need. Help me choose an intensifier.
