Dipper Valve - Model ESD - Valve for Natural Gas Pipeline Security
The ESD valve is a crucial security component for natural gas exploitation and treatment facilities, designed to protect pipeline systems by automatically closing when system pressure exceeds or falls below critical limits, preventing potential damage or gas leaks. It adheres to rigorous design specifications including API 6D, API 608, BS5351, ANSI B16.34, and GB 12237, ensuring its reliability and safety. Available in nominal diameters ranging from DN50 to DN100 (NPS2” to NPS4”) and pressure ratings from PN1.6 to PN42.0 MPa (Class150 to Class2500), the valve features a self-supporting actuator for enhanced operational integrity. Key design improvements include a gas-oil cylinder to prevent freezing and blockage, adjustable pressure shut down settings, and emergency operation capabilities, all backed by national innovation fund and Sichuan provincial support, ensuring a secure and efficient natural gas flow management.

ESD VALVE play a role as the first security protection for natural gas exploiting well and treatment station,are main used to protect the security of pipeline system.when system pressure exceeds the highest limitation,the valve will automatically closed to prevent the device been damaged because of overloaded pressure.meanwhile,when the system pressure is lower than the lowest limitation,the system device may already damaged for kinds of factors,in this case,the valve will automatically closed to prevent natural gas (medium) leakage.
- .Sufficient condition designing and scientific selecting of material ensure the strength,rigidity and service life of each component of valve.
- Scientific oil selecting and set of high-low pressure spring in control system
- Avaiable to set high pressure shut down value and low pressure shut down value at site
- Operate emergency button,can emergency shut down the valve at anytime
- The national patent design gas-oil cylinder（pressure signal translating system）prevent the frozen and blocked,which caused by high containing liquid in medium
- Main valve design ensure the stable shut down performance under emergency
