Product Description

Slow-closing check Valve slow-closing check valve new and reasonable structure, reasonable use of hydraulic principle control theory, stable and reliable work, large flow, disc quick open and slow close, no water hammer impact (closing time adjustable) , good sealing effect, long service life, convenient installation and maintenance. H3 slow closing check valve opening and closing speed control, when the start or stop machine operation, can cooperate with the field adjustment to the best opening or closing speed. Can Be used for high-rise buildings, reduce water hammer and water hammer phenomenon, to achieve the effect of quiet closure. Installation of slow closing check valve: 1. Install the strainer before the slow closing and silencing check valve. 2, installation should pay attention to the direction of the Arrow valve body and the direction of the water flow. In order to facilitate maintenance, check valve should be left around, space. 3. A cut-off valve of the appropriate size should be installed where the water supply can be cut off to ensure maintenance of the check valve. H300X SLOW-CLOSING CHECK VALVE COMMISSIONING: H300X SLOW-CLOSING CHECK VALVE FACTORY, the needle valve and control valve are all closed, using the needle valve grain hour-and-a-half rotation 2 times, Control Valve (ball valve) half open, if found water hammer phenomenon can be fine-tuned to close small control valve, counter-clockwise fine adjust open big needle valve, use water hammer phenomenon H300x slow-closing reverse valve parameters nominal pressure: 1.0 MPA, 1.6 MPA, 2.5 MPA SHELL TEST PRESSURE: p = 1.5 MPA sealing surface test pressure: P = 1.1 MPA MEDIUM: water temperature: 0≤80 °C
