Product Description:
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.
Performance Features:
1. Sufficient condition designing and scientific selecting of material ensure the strength, rigidity and service life of each component of valve.
2. Scientific oil selecting and set of high-low pressure spring in control system
3. Avaiable to set high pressure shut down value and low pressure shut down value at site
4. Operate emergency button, can emergency shut down the valve at anytime
5. The national patent design gas-oil cylinder（pressure signal translating system）prevent the frozen and blocked, which caused by high containing liquid in medium
6. Main valve design ensure the stable shut down performance under emergency
