J- 閥體半保溫
B- 閥體全保溫
HLSJ(B) 保溫夾套小口徑單座調節閥適用于需要保溫的場合。當工藝介質的結晶溫度低于環境溫度或流體溫度降低,造成粘度增加或流體出現凝固時,這時在閥體和上閥蓋處增設蒸汽保溫夾套裝置,使工藝介質滿足過程過程控制的需要。
調節閥泄漏量符合ANSI B16.104標準。調節閥配用多彈簧薄膜執行機構,其結構緊湊,輸出力大。
產品符合GB/T4213-2008標準。
Steam Jacket Small Port Single Seated Control Valves
J- Segmental Steam Jacket for Valve Body
B- Full Steam Jacket for Valve Body
The model HLSJ(B) Control Valves are applicable for the service requiring heat preservation. When the crystal temperature of fluid is lower than ambient temperature or the fluid temperature is falling, it will cause that the vicidity increases or the fluid frozes solid, then the valve body and bonnet require steam jacket to content with the service 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.
