1.Short pattern design. Valves are served in pipeline, oilfield, station, airport, refinery and chemical industry.2. For full thru-conduit port, suitablefor pigging, wiping and scraping. For valve without deversion, not be suitable for pigging, wiping and scraping. Seats and gate surface self cleaning and self lubricating.3. The valves could be suitable in the condition of high content of sulfide(the content of H2S CO2 is above 500mg/m3)4. Single gate and double floating seats in structure. Double block and bleed option to facilitate complete flushing draining and venting of the valve body cavity.5. The sealing facecan be deposited welding withStellite, and both gate and seats are applied ENP process.6. Equipped aviation rubber (NBR or Viton) on the seats and stem, and filled sealant compound. There are triplicate seal managements,7. The valves can be installed in any direction.8. Tested strictly, no leakage.9. Equipped bearings when Equipped handwheel as operating manner. They are more convenient and less torque for opening and closing.10. Sealing faces are protected from the medium flushing when through conduit gate valves being in the state of long-on and long-off, so their service life are long.11. Optional electric actuator or other actuators for valve open-close operation.12. Designed to allow in-line valve maintenance. Parts are replaceable without removing the valve from the line.13. Packing repairable under full line pressure
