Pneumatic small-diameter cage type single seat regulating valve

Our goal is to become a trusted valve consultant for users. Shanghai Yuhe Valve IndustryPneumatic small-diameter cage type single seat regulating valveSuitable for medium pressure applications where the liquid pressure difference exceeds 3MPa, it is a high-performance regulating valve with a nominal diameter of DN20-25mm; Nominal pressure: PN16-PN64, ANSI 150-600LB, JIS 10K-40K, valve material: 22052507904L, 1.4529254SMo, titanium, C276， Monel, 304, 316, WCB。

Pneumatic small-diameter cage type single seat regulating valveValve cover form

1. Standard valve cover: designed for ordinary working conditions, used for ordinary media such as water, gas, oil, steam, etc.

2. High temperature valve cover: designed for high temperature working conditions, the contact area between the valve cover and the surrounding air is increased through heat dissipation fins, which plays a role in heat dissipation.

3. Low temperature type valve cover: suitable for media at low temperatures (such as liquid nitrogen, etc.), this type of valve cover can effectively protect the packing and actuator. The standard material is 304 or 316, and different expansion coefficient materials can also be used according to the working conditions.

4. Bellows valve cover: The metal bellows sealed valve cover is equipped with stainless steel bellows components, which isolate the medium from the remote point boundary and ensure that the valve stem can move up and down. In addition, there is still a standard packing box inside the upper valve cover to ensure that there will be no waste or environmental pollution caused by medium leakage.
