HYDROPACK VBCD DE A Double Overcentre Valve (Type A)

The HYDROPACK VBCD DE A double overcentre valve controls the movement of double acting hydraulic actuators and blocks the actuator in both directions. It keeps the descent of the load under control so the load is not carried away by its own weight, and it prevents cavitation of the actuator. Designed for in-line mounting; available in five port sizes from 1/4" to 1".

Key Features

  • Load holding and controlled lowering in both directions
  • Maximum pressure 350 bar, standard setting 320 bar
  • Pilot ratio 1:4.5 (1/4", 3/8", 1/2") and 1:5.5 (3/4", 1")
  • Maximum flow from 25 to 150 l/min
  • Zinc-plated steel body, hardened and ground steel internal parts
  • BUNA N seals, negligible leakage

Frequently Asked Questions

What does a double overcentre valve do?

It controls the actuator movement and blocks it in both directions. The load is not carried away by its own weight, the descent stays under control and the actuator does not cavitate.

What is the standard pressure setting?

The standard setting is 320 bar. The valve setting must be at least 1.3 times the load pressure so that the valve can close even at maximum load pressure.

How is it connected?

Connect V1 and V2 to the supply, C1 and C2 to the actuator to be controlled. Mounting is in-line.

Which port sizes are available?

1/4" (25 l/min), 3/8" (40 l/min), 1/2" (60 l/min), 3/4" (100 l/min) and 1" (150 l/min).

What is the pilot ratio?

1:4.5 for 1/4", 3/8" and 1/2"; 1:5.5 for 3/4" and 1".

What are the body and seal materials?

Zinc-plated steel body, hardened and ground steel internal parts, BUNA N seals.
