Product Description

Pneumatic Actuator With Air Service Unit High Temperature Control Valve


Product Introduction

The ZJHPG pneumatic high temperature control valve is composed of a multi-spring pneumatic diaphragm actuator (or piston pneumatic actuator) and a low flow resistance valve body. The multi-spring actuator has low height, light weight and simple equipment. Pneumatic high temperature control valve is S streamlined flow path, with compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient maintenance, etc. The pneumatic high temperature control valve adopts balance type, the valve plug has good structure, hard to vibrate, low noise, and low sensitivity to temperature. Pneumatic high temperature control valve is especially suitable for occasions where high temperature.

Feature
 

1. Corrosion resistance. Almost able to withstand the corrosion of all media (including concentrated nitric acid and aqua regia).
2. Good sealing performance. Double sealing with bellows and packing to ensure no leakage.
3. The leakage is small. Because the valve core and valve seat adopt soft sealing, it is ensured that there is no leakage.
4. Equipped with HA actuator, with large output force and compact structure.
