Quick Overview

THREE PORT DIVIDER FLANGE TYPE BALL VALVE

Mounting Surface: Unified Code U61 4-Bolt, Code 61, Code 62 0.125 to 3 inches

INSERTA flange type, 3 port diverter ball valves provide a simple means to install a diverter ball valve in a circuit that uses any of the offered 4-Bolt flange mounting patterns. These ball valves can be installed on or between other components such as pumps, motors, actuators, filters, valves, and manifolds by simply and effectively bolting them together. These assemblies eliminate threaded pipe connections, and the adjoining components are face sealed with the preferred leak resistant O-ring.

The INSERTA flange type, 3 port diverter ball valves have two ball seals similar to the 2 port directional control ball valves, one for each port, i.e. ports 0 and 1. The sealing characteristics of these three port valves are similar to the two port valves. The top of the stem has an “L” slot that indicates the direction of the hole that goes through the three port diverter ball valve element that is used to divert flow from port 2 to ports 0 or 1. The ball has a hole on the bottom that is not sealed that accepts flow from port 2 and communicates it with the “L” hole in the ball. When the handle is turned counter-clockwise (CCW) the slot should be in line with port 0, indicating that the flow from port 2 is diverted to port 0. As long as the
pressure in ports 2 and 0 is higher than port 1, port 1 is blocked (and sealed). As the handle is turned clockwise the slot should be in line with port 1 indicating that the flow from port 2 is diverted to port 1. As long as the pressure in ports 2 and 1 is higher than port 0, port 0 is blocked (and sealed). As the handle is turned between its two normal 90° end positions, both ports 0 and 1 have restricted inter-flow from port 2.

With a total understanding of how these diverter valves function, one can consider them for use as a 3 Port Selector valve. This could be possible when selecting flow from either 0 or 1 and directing it to port 2 when the pressure is always lower on the blocked port than is on the flow ports. With this understanding one may find further use for these diverter valves in applications that currently employ 3 way valves.

An offset steel handle is standard, while offset aluminum and straight aluminum handles are available as options. An offset handle is required for use with a lockable stop plate. A universal lockable stop plate is indicated if a flange is to be mounted directly to face 1 of the ball valve. Ball valve handles are packaged separately for mounting by customer. Standard ball valve handle mounting is with port 2 open to port 0 and port 1 closed when the handle is turned counter-clockwise, and port 2 is open to port 1 with port 0 closed when the handle is turned clockwise.

The Code 61 4-Bolt Valves can be mounted and retained in systems that employ Unified Code U61 4 or 2-Bolt Flange Ports and/or Flange Retainers. When used with 2-Bolt systems either of the 2 diagonal bolt holes can be used for mounting and retaining the valve.

These ball valves are of steel construction with a hard chrome plated ball.
