Dwyer Instruments' A-5000 three-way shut-off valve is made of solid gray PVC, has Buna-N seals and a rotating flag handle. The A-5000 can withstand a maximum operating pressure of 125 psi (8.6 bar) and a maximum temperature of 140 degrees (60ºC).
The handle has 180-degree rotation and lies directly over the open port. When the handle is rotated 90 degrees from either port, flow is shut off to both outlet ports. Since the bottom port on the valve is common, the Series A-5000 can be used as a diverter or a selecting valve. These valves can be used to hook three instruments together, as well as testing various gages and transmitters.
