Product catalog summary
Introduction
This document provides installation, operation, and maintenance instructions for Hayward Industrial Products' Natural PPL True Union Ball Valves. It emphasizes the importance of following these guidelines to prevent serious injury.

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

Operating Conditions
Users must consult Hayward literature for pressure and temperature limitations. The maximum fluid velocity is eight feet per second to avoid damage from water hammer effects. Products are designed for non-compressible liquids and should not be used with compressible fluids.

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

Threaded Connections
Threaded connections should follow ASTM and ANSI specifications. Teflon tape should be used on threads, and joints should be tightened with a strap wrench to avoid excessive stress.

Flanged Connections
Flange bolts should be tightened to compress the gasket without stressing the flanges. A recommended torque table is provided for different sizes.

Adjustment and Repair
Extreme caution is advised during adjustments. The system must be depressurized and drained. The document provides instructions for adjusting and repairing the valve, including replacing o-rings and seals.

Recommended Torque
A table is provided with recommended valve stem torque values for rotating the ball 360° after reassembly.

Components Required
The document lists the components required for assembly, including o-rings, seats, and the valve body.

True Union Ball Valves - PPL Construction-1

1. Hayward guarantees its products against defective material and workmanship only. Hayward assumes no responsibility for damage or injuries resulting from improper installation, misapplication, or abuse of any product. 2. Hayward assumes no responsibility for damage or injury resulting from chemical incompatibility between its products and the process fluids to which they are subjected. Compatibility charts provided in Hayward literature are based on ambient temperatures of 70F and are for reference only. Customer should always test to determine application suitability. 3. Consult Hayward literature to determine operating pressure and temperature limitations before installing any Hayward product. Note that the maximum recommended fluid velocity through any Hayward product is eight feet per second. Higher flow rates can result in possible damage due to the water hammer effect. Also note that maximum operating pressure is dependent upon material selection as well as operating temperature. 4. Hayward products are designed primarily for use with non-compressible liquids. They should NEVER be used or tested with compressible fluids such as compressed air or nitrogen. 5. Systems should always be depressurized and drained prior to installing or maintaining Hayward products. 6. Temperature effect on piping systems should always be considered when the systems are initially designed. Piping systems must be designed and supported to prevent excess mechanical loading on Hayward equipment due to system misalignment, weight, shock, vibration, and the effects of thermal expansion and contraction. 7. Because PVC and CPVC plastic products become brittle below 40F, Hayward recommends caution in their installation and use below this temperature. 8. Published operating torque requirements are based upon testing of new valves using clean water at 70F. Valve torque is affected by many factors including fluid chemistry, viscosity, flow rate, and temperature. These should be considered when sizing electric or pneumatic actuators. 9. Due to differential thermal expansion rates between metal and plastic, transmittal of pipe vibration, and pipe loading forces DIRECT INSTALLATION OF METAL PIPE INTO PLASTIC CONNECTIONS IS NOT RECOMMENDED. Wherever installation of plastic valves into metal piping systems is necessary, it is recommended that at least 10 pipe diameter in length of plastic pipe be installed upstream and downstream of the plastic valve to compensate for the factors mentioned above. > Threaded end connections are manufactured to ASTM specifications D2464-88. F437-88 and ANSI B2.1. Wrap threads of pipe with Teflon tape of 3 to 3-1/2 mil thickness. The tape should be wrapped in a clockwise direction starting at the first or second full thread. Overlap each wrap by, 1/2 the width of the tape. The wrap should be applied with sufficient tension to allow the threads of a single wrapped area to show through without cutting the tape. The wrap should continue for the full effective length of the thread. Pipe sizes 2 and greater will not benefit with more than a second wrap, due to the greater thread depth. To provide a leak proof joint, the pipe should be threaded into the end connection ԓhand tight. Using a strap wrench only > . (Never use a stillson type wrench) tighten the joint an additional 1/2 to 1-1/2 turns past hand tight. Tightening beyond this point may induce excessive stress that could cause failure. 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.

Using a strap wrench only > the joint may be tightened 1/2 to 3/4 of a turn past hand tight. REPAIR: Follow the adjustment sequence and information above, but rotating the seal retainer completely in the loosenӔ direction and remove it from valve body. The o-rings and seals are now accessible for replacement using a sealӔ repair kit. Carefully remove the o-rings from their respective locations taking care not to scratch their sealing...
