Features
Flow-Tek provides Gate Valves with Pneumatic, Electric (Motorized), or Gear Operation, equipped with limit switches. Designed to meet specific operational needs,these valves ensure precise control, reliable performance, and long-lasting durability in demanding industrial applications.
All valves come with extended bonnets featuring a sufficient gas column, tailored to customer specifications. This keeps the stem packing safely away from cold fluids, ensuring consistent performance and durability even in demanding conditions.
- Heavy-duty construction with double flanged or butt-weld ends and outside screw, rising stem yoke-type bonnet.
- Innovative back-seating bush design allows repacking without interrupting operations.
- Robust and reliable, built to withstand demanding industrial conditions.
- Streamlined flow for low pressure drop and efficient operation.
- Leak-proof performance ensures long-lasting service and dependable operation.
