WV and WVC shuttle valves
check valve
RK and RB spiral plug-in check valves
Flow Qmax=120I/min
Work pressure pmax=700bar
1. Overview
This type of one-way valve is individually screwed into a screw hole with a bottom hole shoulder, processed by a drill bit. The valve hole shoulder at the top corner is sealed with an O-ring.
This plug-in valve body consists of two components, which are connected in a convex (RK) shape or pre pressed manner between the components. There is a hemispherical valve core located between them by spring preloading force, which is made of rolled stainless steel, quenched and polished; Similarly, its valve seat has also undergone quenching and grinding.

Flow Qmax=80I/min
1. Overview
Unidirectional valves are divided into two categories;
---CRK and CRB type general one-way valves
----CRH type hydraulic control one-way valve
The common feature is that the valve component is screwed into a simple threaded hole The sealing between its inlet and outlet is achieved through the valve component
The sealing edge at the front end is achieved through precise contact with the stepped shoulder of the threaded bottom hole during installation. The stepped shoulder is formed when drilling ordinary steel parts
118. Bottom hole slope The bottom hole used for installing seals and the sliding slope do not need to be hinged
The external sealing and locking of the screw in valve are achieved using sealing nuts with threaded seals and O-rings
When using hydraulic pressure relief to reverse open, the entire flow section of the valve port quickly opens. In order to intermittently open under high pressure and avoid possible pressure relief impacts, the diameter of the control oil channel on the plug-in body should be made as small as possible to form a throttling pipeline characteristic The valve with specification 3 forms a throttling point on the z oil passage
For high-pressure and high flow loads, specification 3 can be used with a pre relief structure. During the relief process, a small one-way valve opens before the main valve port. Through this smaller overcurrent section, the load pressure can be gradually relieved by impact The additional throttling of the control channel improves the effectiveness of pre pressure relief

1. Overview
A one-way valve allows liquid flow to pass in one direction and stop in the opposite direction (DINISO1219-1).
