Stainless Steel Check Valve

Stainless Steel Check Valve

Introduction:

Stainless steel check valve is suitable for pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with a pressure of 1.6~25MPa and a working temperature of -29~+550℃. The applicable medium is water, oil, steam, and acidic medium, etc.

Selection:

1. Generally suitable for clean medium, not suitable for medium containing solid particles and high viscosity.
2. For low pressure check valves below DN50mm: butterfly check valves, vertical lift check valves and diaphragm check valves should be used; for medium and low pressure check valves with DN greater than 200mm and less than 1200mm, non-return valves should be Wear spherical upper return valve; for low pressure check valve with DN greater than 50mm and less than 2000mm, butterfly check valve and diaphragm check valve should be used.
3. Diaphragm check valve is suitable for pipelines that are prone to water hammer. The diaphragm can well eliminate the water hammer caused by the reverse flow of the medium, but it is generally used in low-pressure and normal-temperature pipelines due to temperature and pressure restrictions.
4. For pipelines that require less water hammer or no water hammer when closed, slow-closing swing check valves and slow-closing butterfly check valves should be used.
