Several representative types of pressure reducing valve (Figure)

What are the typical types of pressure reducing valves? As follows: 0232 Piston pressure reducing valve model, nickel plated brass, PN16, outlet pressure 1-5.5bar adjustable, the most compact inlet valve models, cost-effective, can be connected to pressure gauges, widely used in high-rise buildings Of the pressure reducer; 0234 piston type pressure reducing valve, brass, with double live knot, easy to install, PN25, outlet pressure 0.5-5.5bar adjustable, can be accessed by pressure gauges, widely used in high-rise buildings and branch pipe Dry pipe decompression; 0226 diaphragm pressure reducing valve model, brass, PN25, outlet pressure 1.5-7bar adjustable, can be accessed by pressure gauge, widely used in high-rise buildings branch and trunk decompression; 0204 diaphragm Pressure reducing valve type, brass, PN40, outlet pressure 1-7bar adjustable, can be accessed by pressure gauges, widely used in high-rise buildings branch and trunk decompression; 0204 diaphragm low pressure regulator model, Brass material, PN10, outlet pressure 0-1bar adjustable, can be accessed by pressure gauge, widely used in precision equipment, breeding rooms, laboratories; for pipeline decompression, in the case of partial pressure or sudden pressure water , To protect the students afterwards Process water. High-rise building water supply, solar water heaters, water supply systems, equipment and so on. Piston and diaphragm type two pressure reducing valve Model:
