Operation

The operator provides control force to the regulator valve piston which adjusts, by linear motion, the position of the seal rings in relation to the ports on the flow plates.

Manual:

Adjustment handle can be threaded in or out to increase or decrease the compression on a spring.

Hydraulic Pilot:

A single adjustable hydraulic signal operates on a piston with a 1:1 ratio which allows for simple operation. Requires a small accumulator in the pilot circuit.

Air Diaphragm:

A single adjustable air signal operates a rubber diaphragm.

Motor / Gear Drive:

Gear drive actuator powered by a pneumatic or hydraulic motor provides a failsafe feature with manual override in the event of loss of control signal. The compression spring operates the same as the manual operator.

  • Allows smaller more portable panel to be constructed.
  • Eliminates leak points as there is minimal tubing required
  • Manifolds are supplied pre-assembled and tested giving considerable cost reduction in tubing and assembly costs.
  • Ease of maintenance, only two screws attach the valves to the manifold. No tubing has to be disconnected.
  • Interfaces with existing air cable assembllies.
  • Available in 3-station (#6 tube cable) thru 12-station (#24 tube cable) sizes.
  • Porting is 1/4" NPT for air supply and gauge ports.

Proven Bladder Accumulator Technology

Accumulator Bladder Function

FUNCTION

Fig 1: Bladder is precharged with nitrogen gas and completely fills the shell.
Fig 2: Pump delivers pressurized hydraulic fluid which compresses the bladder to rated working pressure.
Fig 3: Hydraulic fluid is delivered to a system function by the expanding nitrogen gas.
