Product Description

1. Purpose Mainly used for water supply and drainage, also for transport of petrochemical fluid. It has function of cut-off valve, check valve and water hammer eliminator, which can effectively improve system security and reliability and meet automatic control requirement of exit fluid when starting or stopping the pump. 2. Characteristic a. When the pump stops or opens, the valve can be run automatically in accordance with the laws of the pump action. No manual, electric, pneumatic and hydraulic, not manually, with effect of automatic slow opening, fast closing and slow closing, which ensure safe and reliable operation. b. Identified with the signal bar, the valve can automatically display operation status. c. No major obstacles in waterways, small water resistance, so energy saving effect remarkable d. Simple and reasonable structure, easy installation, long service life. 3. Technical parameters a. Nominal pressure: 1.0 1.6 2.5 4.0MPa b. Minimum operating pressure: 0.*5MPa c.
