Trunnion-mounted ball valve
A related on/off valve option where the requirement is isolation rather than characterized V-port control.
Suitable industrial isolation duties
A trunnion arrangement supports the ball mechanically. The supplied flyer identifies the HQ47 as a bidirectional on/off design. Double block and bleed, cavity relief, fire-safe testing and emission performance must be specified and demonstrated separately.
