Pneumatic spring-return ball valve for 1 in lines

This pneumatically actuated ball valve uses a spring-return mechanism to move to a fail-safe position when supply air is lost. The bronze body with 316 stainless-steel ball and PTFE seats handles water, oil and gas service in industrial and commercial piping. It is suited to plant engineers and maintenance teams needing reliable shut-off on 1 in FNPT connections.

Inline 3-piece body with FNPT ends simplifies

The inline 3-piece design lets technicians remove the centre section for seat or seal replacement without cutting pipe. Full-port flow reduces pressure drop and resists clogging in dirty media. Alignment of the pneumatic actuator to the valve stem must be checked during installation; misalignment causes premature stem seal wear and air leakage at the 80 psi supply.

Bronze body rated 600 psi CWP holds under

The valve withstands a continuous working pressure of 600 psi and a maximum inlet pressure of 300 psi across a temperature range of -4 to 176 degrees F. PTFE and Viton body seals maintain integrity during extended cycling, while the NEMA 4X rated actuator resists wash-down and corrosion in harsh environments. Spring-return action remains consistent over long duty cycles without drift.

Questions about this item

How can I verify the PVA65AMS024A valve is actuating correctly after installation?

Apply 80 psi pneumatic supply and confirm the valve strokes fully open and spring-returns to the closed position; the NEMA 4X actuator housing protects the mechanism in wash-down environments.

What components are included with the PVA65AMS024A and what must be sourced separately?

The valve ships as a complete 3-piece bronze body with 316 stainless steel ball, PTFE seats and spring-return pneumatic actuator; piping, FNPT fittings, 80 psi air supply and filtration are not included.

Which pressure and temperature ratings should guide selection of the PVA65AMS024A for my application?

Choose this model when the system operates up to 600 psi CWP, 300 psi maximum inlet pressure and a media temperature range of -4 to 176 degrees F with 80 psi available actuator supply.
