HYDRAULIC CHECK VALVES
Hydraulic Check Valves
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:
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.

TEST POINTS AND TEST HOSE ASSEMBLIES
Test Points and Test Hose Assemblies
Pressure is one of the most important diagnostic parameters in the hydraulic circuit. Obtaining pressure readings is essential to successful preventive maintenance and troubleshooting. The Spradow test points allow the connection of a pressure gauge in only seconds while the equipment is running. It is the safest, cleanest and most convenient way of measuring pressure. Designing your equipment with the Spradow test points will improve the quality of your equipment and in today’s market, higher quality makes the equipment more attractive to potential buyers. The spring loaded check valve inside the test point opens during engagement of the special micro-bore hose fitting end. The connection can be performed under pressure without the use of tools. A single gauge connected to the high pressure micro-bore hose can check an unlimited number of test points. We also offer various types of hose assemblies for direct connection to the test fitting.

BUTTERFLY VALVES
Butterfly Valves
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.
Standard Specifications:
Hydraulic Butterfly Valves Features:
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.

HYDRAULIC RUBBER COMPENSATORS
Hydraulic Rubber Compensators
The HydroWer 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 HydroWer 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 115 psi from -4 °F to +176 °F

SERV-CLIP® HOT TAP CONNECTION
Serv-Clip® Hot Tap Connection
The Serv-Clip® tube measuring connection is used to add a test point on an existing hydraulic circuit within 3 minutes—no cutting of pipes, even if the system is pressurized to 9,100 psi (630 bar). Then carry out your measurements: pressure, flow rate, leakage, temperature, oil sampling or connect a variety of measuring devices.
Required tools for installation: 6mm allen wrench and jaw wrench SW22
Models: Serv-Clip® Type 1 (Installation on pressurized pipes):
Used for sensors with G1/4″ thread
Serv-Clip® Type 2 (Installation on non-pressurized pipes):
Used for sensors with G3/8″ thread
Diameters Available:
The flow rate and leakage sensor functions through the calorimetric principle and can be installed with the Serv-Clip tube measuring connection Serv-Clip® (type 2) in 5 Minutes without cutting pipelines and only requiring the pressure of the hydraulic system to be removed while the needle is piercing the pipe or tube and while the sensor is being installed. The output signal is 4 to 20mA and is calibrated according to your requirements. With the Flow Rate Sensor (from 0.164 to 16.4 feet per second or from 0.05 to 5 meters per second). The sensors are available in stainless steel and plastic covers:
With the Leakage sensor (from 0.164 to 16.4 feet per second or from 0.05 to 5 meters per second):
