DELCO Three-Way Pneumatic Control Valve, L/T Mix/Divert for Petrochemical HVAC Fine Chemical Industrial Pipeline
Pneumatic three-way control valve is a multi-path valve driven by pneumatic actuator, mainly used for precise adjustment of parameters such as flow rate, pressure, temperature or liquid level of fluid media (such as gas, liquid, steam).
-
Nominal Diameter Range from 25Nm to 300Nm.
-
Valve type : 3-Ways
-
Flange Size: JB77-59
-
Nominal Pressure: ANSI150 300 600Lb (JIS10 20 30 40K)
-
