Hydraulic 10,000 psi valves including Manual Valves, Directional Control Valves, and Relief Valves. These valves are all rated up to 10,000 psi (700 bar), though they can handle pressures much lower.
Hydraulic 10,000 psi valves including Manual Valves, Directional Control Valves, and Relief Valves. These valves are all rated up to 10,000 psi (700 bar), though they can handle pressures much lower.
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.

The Hytorc butterfly valve is a component designed to save time for the technician working on the hydraulic system by not having to drain the reservoir. The valve is designed for low pressure hydraulic lines up to 230 psi and can be installed into the pump suction line or mounted directly on to the hydraulic reservoir for example. The maximum pressure differential on either side of the valve should not exceed 58 psi when the valve is closed.
Hydraulic Butterfly Valves Features:
Thin profile and SAE flange for easy design into hydraulic circuits
Ideal for space limited mobile applications
28% more oil volume than ball valves
Simple maintenance; no reservoir draining
Equipped with a shifter for manual actuation
Easy installation for improved efficiency
Designed for low-pressure suction lines only
Automatic locking mechanism
Optional limit switch
Aluminum body for reduced weight
Low cost for large pipes
NBR seals ensure optimal sealing performance
Options: reservoir flange, limit switch, and threaded adapter brushing inserts

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.

The HYTORC Rubber Compensator is a product that qualifies as one of the best kept secrets of power unit accessories. The compensators are flexible connectors with SAE or DIN flanges that correct pipe alignment problems. They also provide a benefit with damping of vibrations, noises and movements in axial and transverse direction.
The HYTORC Compensator is constructed of an inner liner of a reinforced high strength nitrile rubber (Perbunan). The outer and inside layers are smooth and have an aerodynamic design that eliminates cavitation. Both ends have a vulcanized sealing surface, eliminating the need of additional seals. The maximum operating pressure is 116 psi (6 bar) from -4 °F to +176 °F (-20ºC to 80ºC).
All types of mineral oil products, crude oil, lubricants, coolants, grease, cold water, warm water up to 140ºF (60ºC), water-oil-emulsion, fuels with up to 30% aromatics content
