A check valve is the simplest type of directional control valve used in hydraulic systems. Check valves stop the flow of fluid in one direction and allow free flow in the opposite direction. They are also known as non-return valves.
The needle valve DV-08 is a valve in inline construction design with throttle spindle and turning knob. When the turning knob is screwed out, the flow rate is increased - depending on viscosity and pressure. Throttle and shut-off function in both directions. Qmax = 50 l/min Pmax = 350 bar
The needle valve DV-10 is a valve in inline construction design with throttle spindle and turning knob. When the turning knob is screwed out, the flow rate is increased - depending on viscosity and pressure. Throttle and shut-off function in both directions. Qmax = 60 l/min Pmax = 350 bar
The needle valve with reverse flow check DRV-08 is a valve with throttle spindle and turning knob mounted in inline connection housing. When the turning knob is screwed out, the flow rate is increased - depending on viscosity and pressure. A check valve permits free flow in the other direction.
Qmax = 50 l/min
Pmax = 350 bar
The needle valve with reverse flow check DRV-12 is a valve with throttle spindle and turning knob mounted in inline connection housing. When the turning knob is screwed out, the flow rate is increased - depending on viscosity and pressure. A check valve permits free flow in the other direction. Qmax = 90 l/min Pmax = 350 bar
The needle valve with reverse flow check DRV-16 is a valve with throttle spindle and turning knob mounted in inline connection housing. When the rotary knob is screwed out, the flow rate is increased - depending on viscosity and pressure. A check valve permits a free flow in the other direction. Qmax = 180 l/min Pmax = 350 bar
The throttle check valve DRV-20 is a valve with a throttle spindle and rotary knob in the pipeline housing. When the rotary knob is screwed out, the flow rate is increased - depending on viscosity and pressure. A check valve permits a free flow in the other direction. Qmax = 300 l/min Pmax = 350 bar
Seat type valve in modular construction for vertical stacking assemblies. Hardened metallic seat for leak-free closure.
Interface conforming to
ISO 4401-AB-03-04-A
IS 10187
DIN 24340
Eight models available.
Pilot Operated check valve model CI**** allow free flow in the direction from port A to port B and offer leak free closure in opposite direction. Reverse flow can be achieved by applying Pilot pressure to its port X.
The pilot pressure required at port X to achieve reverse flow from its closed position can be calculated using the formulae given in the technical specifications.
Generally, to achieve smooth decompression of oil in the hydraulic actuator prior to reverse flow, it is essential to keep the pilot pressure as close to the calculated value as possible and the flow controlled.
Seal type valves, internal drain construction. Six sizes in threaded port body. Three size subplate mounting construction. Subplate mounting interface conforms to ISO 5781 (draft).
