H7B41X type hydraulic control check valve
【Product use】
H7B41X-16, H7B41X-16C type hydraulic control check valve is suitable for the return water pipe of atmospheric pressure boiler. It uses the pressure change of the transmission pipeline to control the opening and closing of this valve. This valve is a normally closed valve, which can effectively prevent the boiler from overflowing when the circulating water pump stops working due to sudden power failure or other reasons. It can replace expensive electromagnetic control systems.
