Emergency Shut-Down Ball Valve
Emergency Shut-down Ball Valve-National Technology Innovation Project
Version:ESD
Design Specification: API 6D, API 608, BS5351, ANSI B16.34, GB12237
Nomial Size: DN 15~200 (NPS 1/2”~8”)
Pressure Rating: PN 1.6~48 MPa (Class 150~3000)
Product Description:ESD valve play a role as the first security assurance forexploiting well of natural gas and treatment station.they are mainly used to protect the security of pipe system.when system pressure exceeds the highestlimitation,the valve can automatically close to stop device being damaged because of overloaded pressure.meanwhile,when the system pressure is lower than the lowest limitation,system device may be broken for kinds of factors,the valve can also automatic close to avoid natural gas(medium) leakage.
Main Characteristics:
1.Design Based On Sufficient Conditiones And Scientific Ways Of Selecting
Materials Guarantee Valve Parts Strength,Rigidity And Service Life.
2.Scientific Selection Of Hydraulic Oil And The Springs Settled In The Gas-Liquid Exchanging Cylinder.
3.On-site Adjust The Shut Off Value In High Pressure And Low Pressure.
4.The Emergency Button Can Help Valve's Emergency Shut-Down.
5.Big Diameter Gas-Liquid Exchanging Cylinder Can Avoid Ince Barrier Caused By A Large Amount Of Liquid Contains In The Medium.
6.Major Valve Design Ensure The Reliability Of Valve Been Shut Down When Emergency Happens.
