Quantity: 1 valve What it is A single valve designed to control the flow of liquids or gases in a piping or tubing system. Use it to open, close, or regulate flow as required. Why you need it Provides precise control of fluid or gas flow for repair, replacement, or new installations. Simplifies maintenance and system isolation—one component to stop flow for servicing or adjustments. Helps prevent system downtime by enabling quick shutoff or regulation. Key attributes to check before buying Function: controls, stops, or throttles flow. Confirm the intended function (shut-off, regulating, or check/backflow prevention) matches your needs. Compatibility: ensure the valve’s connection type, thread size, and pressure rating match your system. Verify compatibility with the fluid or gas in use. Size and material: valves come in various sizes and materials (metal, plastic, etc.). Select the correct size and material for temperature, pressure, and chemical compatibility. Performance: verify maximum pressure and temperature ratings and any flow-coefficient (Cv) data as applicable for your application. Practical applications (examples) Residential plumbing: replace a shut-off valve under a sink to isolate fixtures during repair without shutting off the main supply. Irrigation and outdoor systems: control sections of a lawn or garden sprinkler system for efficient watering schedules and maintenance. Light industrial or HVAC systems: isolate pumps, filters, or heat-exchanger circuits during servicing or to regulate system flow. Installation and maintenance notes Match threads or connection type and use appropriate sealant or gaskets per system requirements. Tighten to manufacturer torque specifications to avoid leaks or damage. Inspect periodically for leaks, corrosion, or wear; replace if performance degrades. Ordering guidance Confirm the exact size, material, connection type, and pressure/temperature ratings required for your system before purchase to ensure proper fit and reliable operation.
