Ductile Iron Adjustable And Automatic Pressure Holding And Relief Valve
Product introduction:
500X series of hydraulic pressure holding and relief valve is designed and manufactured by our company's technicians who have absorbed advanced technology and experience from similar types of valves internationally. In terms of transmission, it adopts hydraulic operation and can be started and controlled. The valve body adopts a streamlined design, with small internal head loss. The main feature of this valve is that it can be used as a pressure relief valve or a pressure holding valve.
When making a pressure relief valve, the pressure in the water supply pipe that exceeds the safety setting value of the guide valve can be released, and the pressure in the pipe can be maintained below a safety setting value to prevent damage to the pipeline or equipment due to high pressure or sudden pressure in the pipe. It can be used for pressure relief in high-rise building fire testing circulation systems and other water supply systems to prevent system hazards caused by high water pressure;
When making a pressure holding valve, the upstream water supply pressure of the main valve can be positioned above a certain set value to ensure the pressure in the upstream water supply area of the main valve. In short, this product is an ideal product for water supply system.
Product technical parameter:
| Nominal Diameter DN (mm) | 50~300 | |
| Nominal Pressure PN (MPa) | 1.6/2.5 | |
| Test Pressure (MPa) | Strength (water) | 2.4/3.8 |
| Enclose (Water) | 1.8/2.8 | |
| Open and close pressure difference | ≤0.1MPa | |
| Working temperature | 0~80℃ | |
| Medium suitable | Water | |
Product features:
1. The valve body adopts the whole passage, streamlined design, small fluid resistance, large flow.
2. Dual sealing between valve body, bonnet, piston cylinder connection by sealing gasket and the sealing ring sealing, ensure no leakage.
3. The valve body, a piston cylinder, piston double orientation, movement is stable and reliable.
4. The entire stainless steel piston cylinder, the whole cast pistons, NBR sealing ring, a perfect combination of prolonging the service life greatly.
5. The introduction of foreign advanced technology of removable seats, artful structure, has the advantages of novel design, convenient repair and replacement.
6. The band back bore in the piston cylinder, appropriate to increase the damping piston movement, which tend to be more stable.
