Specifications

Introduction

Three-way automatic change valves come with a T- or L- shaped fluid passageways inside the rotor. The T valve might be used to permit connection of one inlet to either or both outlets or connection of the two outlets. The L valve could be used to permit disconnection of both or connection of either but not both of two inlets to one outlet.

Features

1. Generally one of two slurry pumps is in service and the other is used for spare.

2. A tee automatic change valve replaces the two valves. When one side is opened, no slurry will pass through the other side.

3. It is convenient, practical and also wears well.

Application

It is suitable for slurry, ore dreg, tailing, draining system of all kinds of standby pumps and chemical corrosive medium.

Working pressure:≤0.7Mpa

Working principle

Three-way ball valves have an L-shaped or T-shaped hole through the middle. The different combinations of flow are shown in the figure. It is easy to see that a T valve can connect any pair of ports, or all three, together, but the 45 degree position which might disconnect all three leaves no margin for error. The L valve can connect the center port to either side port, or disconnect all three, but it cannot connect the side ports together.
