The pneumatic control valve core adopts an upward guide structure, with a compact valve structure and S-shaped channels, which reduces pressure drop loss, increases flow rate, has a wide adjustable range, and high accuracy of flow characteristics, in compliance with the IEC534 standard.
Product Details
1、 Pneumatic insulation control valveProduct Overview
The pneumatic insulation control valve core developed and produced by our company adopts an upward guiding structure,Compact valve structure,There is a presentationSStreamlined channel,Make its pressure drop loss small,high traffic,Wide adjustable range,High accuracy of flow characteristics,comply withIEC534Standard. jacket insulationpneumatic control valveSuitable for occasions that require insulation. When the crystallization temperature of the process medium is lower than the ambient temperature or the fluid temperature decreases, causing an increase in viscosity or solidification of the fluid, a steam insulation clamping magnetic device is added to the valve body and upper valve cover to ensure that the process proceeds as required. The leakage of pneumatic insulation control valve complies with ANSI B16.104Standard. jacket insulationpneumatic control valveEquipped with a multi spring thin film actuator, it has a compact structure and high output force. Product compliesGB/T4213-92。
