Key Features

100 %% Bubble-Tight Close-Off

The peroxide-cured EPDM paddle and seals give 100 percent bubble-tight seat close-off leakage at up to 25 psi differential.

5.0 Cv Flow Capacity

Sized at 5.0 Cv, one of five flow capacities in the Z-one range, so the body can be matched to the circuit rather than the pipe size.

Rated to 300 psi and 240 deg F

Forged brass body rated to 300 psi static and 32 to 240 deg F, plus 15 psi low pressure steam.

Push Button Actuator Mount

A Z1 series actuator locks on with a push button and no fasteners, and lifts off for service without breaking the pipe joint.
