SERVICE INSTRUCTIONS FOR
VALV-TROL BALANCED VALVES

These instructions are written for Valv-Trol balanced 2-way valves, in sizes from 3/4” through 4”, with all body constructions, including standard bronze bodies or steel bodies. These procedures are also applicable to our balanced 3-way valves, which have two discs and two seat rings for each valve.

For those who want assistance, or prefer to have the valves professionally serviced,
Valv- Trol offers complete valve repair or reconditioning to new standards.
These services are done on a time and material basis, and usually offer significant savings over new valve prices.

Valv-Trol valves can be repaired without removal from the piping. If the valve is to be repaired in-line, the first step is to remove and lock out all power to the valve. Once all residual pressure is bled off, the repair can begin. If the repair is to be done in a bench vice, care should be taken to not distort the valve body in the vise. Grip the valve body in line with the ports, or screw a length of pipe into the port and hold the pipe in a vise.
