Armaş “NSC” model valve is hydraulically controlled non-slam check valve which operates with line pressure and prevents back-flow in system. Valve works with double chambers. Upstream pressure controls one of chambers and downstream pressure controls the other one. When downstream pressure value exceeds upstream pressure value (back-flow), valve is closed as wholly sealed without causing surge because of double chambers. When upstream pressure value exceeds downstream pressure value, non-slam check valve is opened by itself slowly. So pressure surges formed during start-up, stop and working sysytems are dumped.
The valve will be diaphragm actuated disc closing automatic hydraulic control valve which works with line pressure. Double-chamber diaphragm actuator provides quicker and non-impact opening/ closing thanks to disc-closing valve design and prevents blockage by showing less sensitivity against solid substances within fluid.
Valve size same as main line or one size smaller. Maximum flow speed for continuous operation 5.5 m/sec (18 ft/sec)
