Butterfly Valve Series

Soft Seal Butterfly Valve

Replaceable resilient seat for water and HVAC.

As part of the VTXFLOW butterfly valve range, the soft seal butterfly valve is produced under our certified quality system — from in-house casting and CNC precision machining to 100% pressure and seat-tightness testing before shipment. From resilient-seated centerline valves to triple-offset metal-seat designs, VTXFLOW butterfly valves offer economical flow control in a compact envelope, in wafer, lug and double-flanged bodies.

  • Low weight and short face-to-face saves installation cost
  • Triple-offset design gives frictionless, bidirectional sealing
  • Bare-shaft, gear, electric or pneumatic operation
  • Optional API 607 fire-safe certification
