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 operating conditions.

Installation Guidelines:

Ensure systems are depressurized and drained before installation or maintenance.
Consider temperature effects on piping systems to prevent mechanical loading on equipment.
Use caution with PVC and CPVC products below 40°F as they become brittle.
Avoid direct installation of metal pipes into plastic connections; use plastic pipe sections to mitigate thermal expansion and vibration issues.

Socket Connection: Follow ASTM specifications for solvent cementing. Ensure surfaces are clean and free of contaminants. Apply primer and cement as instructed, and allow adequate set and cure times based on temperature conditions.

Threaded Connection: Use Teflon tape on threads, wrapping in a clockwise direction. Tighten joints using a strap wrench to avoid excessive stress.

Flanged Connection: Tighten flange bolts to compress the gasket without distorting flanges. Use lubricated metal bolts and soft rubber gaskets, following recommended torque values.

Adjustment and Repair: Depressurize and drain the system before adjustments. Follow directional indicators for seal retainer adjustments. For repairs, replace o-rings and seals using a repair kit, ensuring no damage to sealing surfaces.

Torque Requirements: Recommended valve stem torque values are provided for different valve sizes to ensure proper operation.

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. RECOMMENDED FLANGE BOLT TORQUE.
