BUCHER/Guided Check Valve DERV Detailed Introduction

BUCHER/Guided Check Valve DERV Detailed Introduction

Product Description:

DERV series guided one-way valve, used for cylinder locking positioning, supply directly installed on the cylinder

Unidirectional control function and pipeline anti riot valve

Optimize hydraulic guidance to provide smooth opening

Leak free seat valve; Quenching, grinding, and grinding treatment

Load pressure acting in the closing direction

Spring closed, guided, axle type lift valve

It keeps the load in a neutral position without leakage

Prevent load drop during explosion

Appears in feeding tube A or B

DERV 8: Hardened seats and seat cushions

DERV 10: Hardened and ground seats

And prompt

Prevent creep of hydraulic clamping actuators

The working circuit can be closed and maintained in other directions and under pressure

The functions of the guided one-way valve and pipeline rupture valve are integrated into a single unit

Due to optimized compression (pre enable) function, soft enable

Suitable mechanism with threaded port
