- Full bore, through conduit extend valve life and eliminated turbulance and pressure drop.
- Threaded area of rising stem protected from the working fluid and from the atmosphere.
- Permanent contact between the gate and the seats protects against intrusion of particle contaminants seal areas.
- The stem bushing (nut) assemblied on 2 bearings, protected from the working fluid and permanently greased, provide low operating torque.
- Drain plug/greaser and air plug/greaser provide the current maintenance, low operating torque and increased service life.
- Bypass assembly shall prevent the pressure in the cavity exceedeing.
- Visual position indicator. At the purchaser’s requests the standard variant can be completed with position sensors.
