Product Name
Pneumatic Angle Seat Valve – 316 Stainless (CF8M), PN40, Steam On/Off, 1/2″–2″
Product Summary
Pneumatic angle seat valve (Y-type) in 316 stainless steel with an integrated air piston — a pneumatic steam valve for fast on/off of high-pressure steam, hot water and liquids. The inclined seat gives high flow and low pressure drop.
CF8M (316) body · PN40 · −20 °C to +150 °C · 1/2″ – 2″ (DN15 – DN50) · threaded or welded ends
Made in Taiwan. No MOQ. Dimension drawing and full size table are below.
The YZNG TRONG Pneumatic Angle Seat Valve (also known as a Y-type valve) is a 316 stainless steel on/off valve driven by an integrated air piston. Its inclined Y-pattern seat opens a near-straight flow path, giving high flow and low pressure drop — which is why the angle seat valve is a common choice as a pneumatic steam valve for fast, frequent on/off duty.
The piston actuator snaps the valve open and shut for automated lines, and the all-stainless wetted parts handle high-pressure steam, hot water and other liquids. Threaded ends make it quick to install or replace in existing pipework.
Built for Steam and Hot Fluids
- Steam service: the angle-seat design and stainless build suit high-pressure steam and hot-water on/off (not a modulating control valve).
- High flow: the inclined seat gives a near-straight path and lower pressure drop than a globe valve.
- Fast cycling: the integrated piston handles frequent open/close on automated lines.
- Durable head: piston actuator available with a stainless steel or engineering-plastic head.

Applications
Steam on/off lines, hot-water and CIP systems, bottling and food processing, machinery and OEM skids — anywhere a fast, high-flow pneumatic on/off valve is needed for steam or hot fluids.
FAQ
Is this a control (modulating) valve? No. It is an on/off angle seat valve — fast, tight shut-off for steam and hot fluids, not proportional control.
Why an angle seat valve instead of a globe valve? The inclined seat opens a near-straight path, so flow is higher and pressure drop lower, and the piston handles frequent cycling.
Why does 1″ (DN25) appear twice in the dimension table? It comes with a choice of two actuator sizes. The valve body is the same; the larger actuator delivers more closing force for higher working pressure differentials, which changes the overall height (H) and length (L).
What temperature can it handle? −20 °C to +150 °C, which covers saturated steam and hot-water service in that range.
