BRASS HAND SHUT OFF VALVE

Product Description

Hand Shut-Off Valve: Technical Overview

A Hand Shut-Off Valve is a fundamental flow control component used to manually start or stop the flow of liquids or gases within a system. These are critical for safety, maintenance, and operational control.

Key Material Considerations

Selecting the right material is essential for durability and chemical compatibility:

• Brass: Excellent for HVAC, refrigeration, and non-corrosive plumbing. It offers good ductility and corrosion resistance.

• Stainless Steel: Ideal for high-temperature, high-pressure, or corrosive environments (e.g., chemical processing).

• PVC/CPVC: Used in residential plumbing and irrigation for lightweight, cost-effective water control.

Technical Specifications to Check

When sourcing or installing a hand shut-off valve, ensure you verify the following:

1. Connection Type: * NPT (National Pipe Thread): Tapered threads for a tight seal.

   • Flare: Often used in HVAC/R for leak-proof metal-to-metal joints.

   • Compression: Used in plumbing for easy installation without soldering.

2. Pressure Rating: Usually measured in PSI or BAR.

3. Temperature Range: Vital for steam or refrigeration applications.

4. Seal Material: Common seals include PTFE (Teflon), Viton, or EPDM, depending on the chemical nature of the fluid.
