FREE-Valve’sDouble Offset Butterfly Valvescan be used for shut-off and throttling control.Itcan ensure sealing more reliable and achievenon-leakagebecause of theresilient-seateddesign.Thebutterflyvalve can realize rotary under the condition of low torque bytheresilient-seateddesign,which means a longer service life,so as to cost-effective of choosing actuator.
Features
1. Reliable sealing, convenient operation, opening and closing fast.
2.The valve’sseatisavailable inmetal,PTFEandgraphite PTFE,whichmakes the valve suitable for liquidorgas service withmanyapplications
3. Theresilient-seateddesign ensures minimal seat wear and double offset disc design provides excellent throttling capabilities,ithascharacteristic ofsuper long usage life, frictionless closure,high temperature etc.
4. Blowout proof shaft design and the application of self lubricated bearings.
5.Preventing the disc fromclosingunderover/under travel byadjustingmechanical stopper.
