Piston Actuated Valves
PAV Operating:
These compact on/off valves provide tight shut-off by utilising a PTFE plug seal. Valve stem sealing is achieved through self-aligning PTFE chevrons to maximise sealing integrity.
These Valves ensure leakproof isolation up to the range of ANSI class VI. (i.e. bubble tight shut off)
Normally closed and normally open versions are available plus a version for special bi-directional flow and anti-water hammer
Applications is available. Additional options include a flow regulator, travel switch and directly mounted solenoid pilot valve.These valves can be used on a wide range of media including steam, air, oil and other fluids, and can operate at a maximum temperature of 180°C and pressure ratingsof PN 25 (upto 1") & PN 16 (11/2" & 2").
Normally Closed:
These valves are designed for flow over the seat (port 1 to 2).
Not recommended for water-hammer prevention.
Normally Open:
These valves are designed for flow under the seat (port 2 to 1).
Can be used to prevent water-hammer on valve closure in liquid applications.
Bi-Directional Normally Closed:
These valves are designed for special applications that require flow in both directions (port 1 to 2 or port 2 to 1) and incorporates an
anti-waterhammer design for liquid applications flowing under the seat (port 2 to 1).
