TeeJet 23120-3/4-PP Pressure Relief Valve Instruction Manual

1. Introducció

This instruction manual provides essential information for the proper installation, operation, and maintenance of the TeeJet 23120-3/4-PP Pressure Relief Valve. Adhering to these guidelines will ensure optimal performance and longevity of the product. Please read this manual thoroughly before using the valve.

2. Informació de seguretat

Avís: Always depressurize the system before attempting any installation, adjustment, or maintenance on the valve. Failure to do so can result in serious injury or equipment damage.

• Wear appropriate personal protective equipment (PPE) when handling the valve and working with pressurized systems.
• Ensure all connections are secure and leak-free before operating the system.
• Do not exceed the maximum operating pressure specified for this valve.
• Consult a qualified professional if you are unsure about any installation or operation procedures.

3. Producte acabatview

The TeeJet 23120-3/4-PP is a piston-type pressure relief/regulating valve designed to control line pressure by bypassing excess liquid. It features an adjustable design for precise pressure control and is constructed with durable materials for chemical resistance.

Figura 1: TeeJet 23120-3/4-PP Pressure Relief Valve. This image shows the black polypropylene body of the valve with a white adjustment knob at the top. It has a 3/4-inch inlet/outlet connection and a 1/4-inch FPT gauge port.

Característiques principals:

• Piston-type design for effective pressure regulation.
• Adjustable pressure setting with a secure locknut.
• Extra-large valve passages for handling large flow rates.
• Constructed with a 302 stainless steel spring and EPDM O-ring for chemical resistance.
• Includes a 1/4" port for pressure gauge pipe plug for convenient monitoring.
• Inlet and Pipe Connection: 3/4"

4. Configuració i instal·lació

Proper installation is crucial for the safe and efficient operation of the pressure relief valve. Follow these steps carefully:

1. Sistema de despressurització: Ensure the entire system is depressurized and isolated before beginning installation.
2. Seleccioneu la ubicació: Install the valve in a location that allows for easy access for adjustment and maintenance. It is typically installed at the tank return or bypass line.
3. Preparar connexions: The valve features 3/4" inlet and pipe connections. Apply appropriate thread sealant (e.g., Teflon tape) to all threaded connections to ensure a leak-free seal.
4. Connect Valve: Securely connect the valve to the system piping. Ensure the flow direction is correct, if applicable.
5. Install Pressure Gauge (Optional): If desired, install a pressure gauge into the 1/4" FPT gauge port to monitor system pressure. Use appropriate thread sealant.
6. Inspeccionar connexions: Visually inspect all connections for tightness and proper alignment.
7. Sistema de pressurització: Slowly re-pressurize the system and check for any leaks. Address any leaks immediately before proceeding.

5. Instruccions de funcionament

The TeeJet 23120-3/4-PP valve functions by bypassing excess fluid to maintain a set pressure. It is designed to regulate pressure rather than simply release it and then close completely.

1. Configuració de la pressió inicial: With the system operating, turn the white adjustment knob (visible at the top of the valve in Figure 1) clockwise to increase the set pressure or counter-clockwise to decrease it.
2. Monitor de pressió: Use a pressure gauge connected to the 1/4" port to accurately monitor the system pressure while making adjustments.
3. Secure Setting: Once the desired operating pressure is achieved, tighten the locknut located beneath the adjustment knob to secure the setting and prevent accidental changes.
4. Funció de bypass: Understand that this valve will continuously bypass fluid once the set pressure is reached, maintaining that pressure by diverting excess flow. It does not fully close after a pressure spike.

6. Manteniment

Regular maintenance ensures the reliable operation and extends the lifespan of your TeeJet pressure relief valve.

• Inspecció periòdica: Periodically inspect the valve for any signs of wear, damage, or leaks. Check the integrity of the polypropylene body and connections.
• Neteja: If the valve is exposed to corrosive chemicals or debris, flush it with clean water after use to prevent buildup and corrosion.
• O-Ring and Spring Check: The valve contains a 302 stainless steel spring and EPDM O-ring. If pressure regulation becomes inconsistent or leaks occur, these components may need inspection or replacement.
• Emmagatzematge d'hivern: If the valve is part of a system that will be stored in freezing conditions, ensure all water is drained from the valve and associated plumbing to prevent damage from ice expansion.
• Substitució de components: Use only genuine TeeJet replacement parts for any repairs to ensure compatibility and performance.
