The Z641Y gate valve uses a flat gate moving vertically to open and close. Its full-bore, low-resistance straight-through passage is suitable for pipeline pigging. The valve provides reliable sealing, high operating torque capability and broad media compatibility. An opening-position indicator is standard, and manual, electric or pneumatic actuation can be supplied for different operating conditions.
