Product catalog summary

Introduction: This document provides installation, operation, and maintenance instructions for Hayward True Union Ball Valves. It emphasizes the importance of following these guidelines to prevent injury and ensure proper functioning.

Guarantee and Responsibility: Hayward guarantees its products against defects in material and workmanship but does not assume responsibility for damages or injuries due to improper installation, misapplication, or chemical incompatibility. Users should verify compatibility and suitability for their specific applications.

Specifications: The document outlines the operating pressure and temperature limitations, recommending a maximum fluid velocity of eight feet per second to avoid damage from water hammer effects. It also advises against using Hayward products with compressible fluids.

Installation Guidelines: Systems should be depressurized and drained before installation or maintenance. Consideration of temperature effects on piping systems is crucial to prevent mechanical loading on equipment. Caution is advised when using PVC and CPVC products below 40°F due to brittleness.

Connection Types:

Socket Connection: Follow ASTM specifications for solvent cementing. Ensure surfaces are clean and free of contaminants. The document provides a detailed procedure for applying primer and cement.
Threaded Connection: Use Teflon tape for sealing, wrapping it clockwise with sufficient tension. Tighten joints using a strap wrench to avoid excessive stress.
Flanged Connection: Tighten flange bolts to compress the gasket without distorting the flanges. Use lubricated metal bolts and soft rubber gaskets.

Adjustment and Repair: Extreme caution is advised when adjusting or repairing valves. The system must be depressurized and drained. The document provides instructions for adjusting the seal retainer and replacing o-rings and seals using a repair kit.

Torque Requirements: Recommended torque values for rotating the valve stem are provided for different valve sizes. Proper torque ensures smooth operation and prevents damage.

Components: The document lists required components for assembly, including assembly nuts, end connectors, seal retainers, o-rings, seats, stems, handles, balls, and the valve body.

Flange bolts should be tight enough to slightly compress the gasket and make a good seal, without distorting or putting excessive stress on the flanges. Suitable washers should be used between the bolt head and flange and the nut and flange. Bolts should be tightened in alternating sequence.
