Firefighting Pump
CLA-VAL has been a leading manufacturer of automatic control valves, serving waterworks, fire protection, aviation fueling and industrial customers throughout the world. Main relief valve is designed to relieve excess pressure in a fire protection system, while eliminating the damaging effects of cavitation. The valve features an adjustable pressure setting, fast opening to maintain steady line pressure, and gradual closing for surge free operation. Casing relief valve is designed to relieve excess pressure in a fire protection system, while eliminating the damaging effects of cavitation. The valve features an adjustable pressure setting, fast opening to maintain steady line pressure, and gradual closing for surge free operation. It is typically used in a fire protection system to trim water pressure, thus preventing pressure build-up whenever line pressure exceeds the setting of the spring. It will relieve excess pressure to atmosphere to prevent damage to the distribution network.
