1.0 - INTRODUCTION

The Armstrong Model FTV Flo-Trex Combination Valves are designed for installation on the discharge side of

centrifugal pumps. The Armstrong Combination Valve incorporates three functions in one valve:

• Drip-tight shut-off valve

• Spring-closure design, non-slam check valve

• Flow throttling valve

1.1 - WARNING

These instructions must be read, understood and followed before attempting to install, maintain or operate this

equipment. Otherwise severe personal injury or damage to equipment may result.

Before installing the Flo-Trex valve, make sure that there is enough room provided to disassemble the valve

for maintenance.

Before undertaking any maintenance on the Flo-Trex valve, it must be isolated from the system line and any

pressure must be allowed to normalize to atmosphere.

Valves that remain in one position for long periods of times may be subject to some degree of reduced

operability as a result of loss of effective lubricants in threads, aging of gasket, surface corrosion of moving

parts, or accumulation of foreign solids. Refer to this manual's recommended maintenance section to maintain

valve performance.

2.0 - INSTALLATION

The valve should be mounted to a spool piece on the discharge side of the pump. Spool piece length is based

on a minimum recommended space of 2 times the pipe diameter (e.g.: 350mm discharge requires 350mm D x

711mm L spool piece).
