Frequently Asked Questions

What is an angle seat valve?

An angle seat valve is a pneumatically actuated process valve with an angled flow path designed for efficient on/off media control.

What media can angle seat valves control?

Suitability depends on body, seal and temperature specifications. Common applications include compatible water, air, steam and process fluids.

What is the difference between normally closed and normally open?

A normally closed valve shuts when the pilot signal is removed, while a normally open valve remains open without the pilot signal.

Why choose stainless steel?

Stainless steel provides improved corrosion resistance and is often selected for demanding process, washdown or hygienic environments.

How is the valve actuated?

Compressed pilot air moves the actuator and opens or closes the valve.

How should the port size be selected?

Use required flow, pressure drop, media properties and pipe size to determine the correct valve size.

Can angle seat valves handle steam?

Selected models may be suitable for steam when their body, seal, pressure and temperature ratings are observed.

Can Pneuforce help configure the valve?

Yes. Pneuforce can assist with body material, port size, thread, function, seals and pilot requirements.
