Product Q&A

Q:Cage balanced valve vs ordinary single-seat pneumatic regulating valve

Single-seat has huge medium unbalanced force, cannot withstand large pressure difference; balanced cage offsets most pressure load, stable operation under high P; single-seat achieves tighter zero leakage while cage has slight allowable leakage volume.

Q:Standard signal and air supply

Standard control signal 4-20mA DC; instrument air supply pressure 0.04-0.06MPa; air source needs drying and filtration purification.

Q:Can it achieve full tight shut-off?

Single seat soft seal realizes near bubble-tight shut-off; sleeve type has slight residual leakage, not for strict zero leakage isolation.
