Electric Parallel Double Gate Valve

Technical Requirement:
  1. Design & Manufacture: GB/T 12232
  2. Face-to-Face: GB/T 12221
  3. End Flanges: GB/T 17241.6
  4. Inspection & Test: GB/T 13927

Description

The Electric Parallel Double Gate Valve combines a parallel double-disc gate with a multi-turn electric actuator for remote isolation. The two discs travel parallel to the seats and are expanded against them only at final closure, reducing wear and operating torque. Supplied with limit and torque switches and a manual override, it is a robust choice for automated water and heating systems.

Key Product Features:
  1. Automated Operation: Electric actuator allows remote, local or PLC-controlled opening and closing.
  2. Protected Drive: Torque and travel switches stop the motor at the correct position.
  3. Parallel Double Disc: Low friction travel and tight sealing on both seats.
  4. Manual Override: Handwheel operation during power loss or commissioning.
  5. Large Size Capability: Suitable for big-diameter mains where manual operation is impractical.
Applications:

Ideal for Water Treatment Plants, District Heating, Power Stations, and Metallurgical Plants. Specifically suited for remote isolation of large pipelines.
