Soft-seated V-port ball valve
A soft-seat option for compatible, comparatively clean media where specified shut-off performance is important.
Compatible clean liquids and selected process gases
Soft seats must be chosen for fluid chemistry, temperature, pressure and cycling. The VQ77 wafer flyer lists metal seating only; do not assume every body style accepts the same seat construction.

What to confirm before ordering
- Confirm the actual polymer grade, fillers and manufacturer temperature-pressure limits.
- Disclose solids, solvent mixtures, steam cleaning and cleaning chemicals.
- Agree the leakage test standard instead of relying on the phrase bubble-tight.
One coordinated supply scope
- Valve body, seat, segment and shaft specified against the medium and operating envelope.
- Actuator sized for the required torque and failure response.
- Controls and feedback selected for the plant interface.
- Inspection and documentation identified in the quotation.
