The EP-2600 pneumatic high pressure differential regulating valve is a pressure balanced regulating valve. It is composed of a multi spring diaphragm actuator and a pressure balanced valve core adjustment mechanism. The valve body structure is compact, the fluid channel is S-shaped, and the pressure drop loss is small, the flow rate is large, and the adjustable range is wide. Large output force, suitable for high-pressure fluids, low noise requirements, and automatic regulation and control situations.
Comply with GB/T4213-92 standards, and the leakage rate also complies with ANSIB16 and Prevention 104 standards.
