Angle Seat Valve – Pneumatic Steam Valve, 316 CF8M, PN40, Spring Return, 1/2″–2″

The YZNG TRONG 2000Y is a stainless steel angle seat valve — a Y-type on/off valve in cast 316 (CF8M) driven by an integrated air piston. The inclined seat opens a near-straight flow path, so it passes more flow with less pressure drop than a globe valve of the same size. That is why the angle seat valve is the usual choice as a pneumatic steam valve for fast, frequent on/off duty.

The single-acting piston (spring return) snaps the valve open and shut on automated lines, and the stainless wetted parts with a PTFE seat handle steam, hot water and other liquids from −20 °C to +150 °C. PT threaded ends, 1/2″ to 2″, make it quick to fit or replace in existing pipework.

Built for Steam and Hot Water

• 蒸汽服務： the angle-seat design and 316 build suit saturated steam and hot-water on/off up to 150 °C (not a modulating control valve).
• 高流量： 與球閥相比，傾斜式閥座能提供近乎直線的流路，且壓降較低。.
• 快速循環： the integrated piston handles frequent open/close on automated lines; the spring returns the valve when air is removed.
• 耐用的頭部： 活塞式致動器可選配不鏽鋼或工程塑料製成的頭部。.

主要技術規格

Which actuator you need depends on your working pressure differential: tell us your line pressure and pilot air pressure when you request a quote, and we will size the actuator for you. Full dimensions are in the PDF dimension sheet above.

應用

• Low-pressure saturated steam on/off — steam supply to jacketed vessels, heating coils and process equipment, within the 150 °C rating.
• Hot-water heating circuits — fast, tight shutoff on hot-water loops and heat exchangers.
• Sterilizer utility lines — condensate, vent and coolant lines on sterilizers and autoclaves.
• Washdown and rinse circuits — on/off control of hot-water and rinse lines in cleaning systems.
• Filling and bottling lines — frequent cycling on filling, bottling and canning machines.
• Industrial laundry and textile finishing — steam and hot-water on/off on washers, dryers and dyeing machines.
• Cooling water and heat exchangers — including mould-cooling water on injection moulding machines.
• Compressed air, viscous and particle-laden media — the straight-through Y pattern passes thick or dirty fluids that would clog a globe valve.

Fit a stainless steel Y strainer upstream to keep scale and debris off the seat. For quarter-turn shutoff on liquids and gas, see our 氣動球閥.

常見問題

這是控制（調節）閥嗎？ 不，這是一款開關式角座閥——適用於蒸汽和高溫流體的快速、緊密截止，並非比例控制。.

為何要使用角座閥而非截止閥？ 傾斜式座圈形成近乎筆直的流道，因此流量更大、壓降更低，且活塞能承受頻繁的往復運動。.

Why is 1″ (DN25) offered with two actuator sizes? The valve body is the same; the larger actuator delivers more closing force for higher working pressure differentials. Tell us your line pressure and pilot air pressure when you request a quote and we will pick the right one.

它能承受什麼溫度？ −20 °C 至 +150 °C，涵蓋該溫度範圍內的飽和蒸汽及熱水應用。.
