🔴 Valves Guide
Valves control water flow, pressure, and direction in plumbing systems. This category includes shut-off valves (ball, gate, globe), check valves (preventing backflow), pressure-reducing valves, temperature and pressure relief valves, mixing valves, and specialty valves for specific applications. Valve types are selected based on function, flow characteristics, pressure requirements, and installation location. Key specifications include valve size, connection type (threaded, soldered, compression, push-fit), pressure rating, and material construction (brass, bronze, stainless steel, PVC). Common applications include fixture isolation, main water line control, water heater safety, and backflow prevention.

Ball Valves
Use a rotating ball with a bore to control flow. Quarter-turn operation provides quick, reliable shut-off. The most common residential shut-off valve.
4 min read Learn more →Check Valves
Allow water to flow in one direction only, preventing backflow. Essential for protecting water supply from contamination.
4 min read Learn more →Mixing Valves
Blend hot and cold water to deliver a safe, consistent temperature. Thermostatic models automatically adjust to prevent scalding.
4 min read Learn more →Pressure Reducing Valves
Automatically reduce incoming water pressure to a safe, consistent level. Protect plumbing fixtures and appliances from damage caused by high pressure.
