Steam Jacket Control Valves
Steam Jacket Control Valves

Steam Jacket Control Valves are applicable for the service requiring heat preservation. When the crystallization temperature of fluid is lower than ambient temperature or the fluid temperature is falling, it will cause the viscosity increasing or the fluid solidified, then the valve body and bonnet require steam jacket units to meet the requirement of process control

The leakage complies with the ANSI B16.104 standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs.

This product complies with the GB/T4213-2008 standards.
