Product Detail

Overview

The Pneumatic High Pressure 3-Way Ball Valve consists of a piston pneumatic actuator and a high pressure ball valve. It can be controlled to open and close by inputting an air supply of 0.4~0.8MPa, enabling remote operation. It is used to shut off the working medium and divert its flow, allowing connection between two mutually perpendicular channels.

Product Features

High pressure resistance, low torque, and rapid switching.
Floating ball design, outlet side sealing, and full flow capacity.
Switch positions are limited by limit pins and pads.
Leak-proof design eliminates the need for manual seal adjustment.
Switch position can be observed via the indicator slot on the handle spindle.
