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。.

最低訂購量是多少？ No minimum order quantity — we accept orders of any size, including small trial orders, and can supply a mill certificate on request. Payment is by T/T — 30% on order confirmation, 70% before shipment.

Stainless steel or engineering-plastic head: which should I choose? Both heads drive the same 316 (CF8M) body, PTFE seat and PN40 rating, so line pressure and fluid temperature limits do not change. Choose the stainless steel head for outdoor installations, washdown areas or hot surroundings. The engineering-plastic head is the lighter, lower-cost option for indoor, dry installations. Tell us where the valve will be installed when you request a quote and we will recommend the right head.
