How do I check valve types?
Valves come in many sizes, materials and gate apertures to control the flow of air, fluids and solids. Determining a valve types involves the valve’s size, construction, rated capability (pressure, flow rate, caustic resistance, etc.) and gate configuration. Valve selection in any application is always comparing price with performance. Installing an inexpensive valve may lead to early problems but installing a valve with over-rated performance characteristics can lead to budget shortfalls.Determining the size of a valveValves are always measured by inside diameter. The outside diameter may vary depending on the wall thickness and material. A one-inch valve in a high-pressure application may appear much larger than a one-inch valve for low- or no-pressure installations. Don’t confuse the overall size of a valve with its rate size. Valve size will also vary depending on the gate. A ball valve (a seated ball in a socket with a hole through the middle that rotates to turn on and off) will
