Pilot-to-open check valve with bypass orifice

SERIES 2 / CAPACITY: 120 L/min. / CAVITY: T-2A

This valve is a pilot to open check valve with a bypass orifice. It incorporates a sealed pilot, a steel seat, and is

non-vented. It allows free flow from the valve (port 2) to the load (port 1) and restricts flow in the opposite direction.

Pressure at the pilot (port 3) will open the valve from port 1 to port 2. The pilot pressure needed at port 3 to open

the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes the pilot

pressure. Note: The bypass orifice diameter is specified by the customer. See Technical Data below for the

allowable orifice range.

TECHNICAL FEATURES

Sealed pilot for use in circuits where cross port leakage is undesirable.

The customer specified orifice diameter is stamped on one of the cartridge's hex faces.

For models with manual load release control option, turn load release clockwise to release load.

This 3 port pilot-to-open check valve and 3 port counterbalance valves are physically interchangeable (i.e. same cavities, same flow path for a given frame size).

However, cartridge extension dimensions from the mounting surface may vary.
