Product Introduction
【Product use】
HDW41X type multifunctional silent check valve is mainly used in high-rise buildings, at the outlet of the pressurized water pump, the valve automatically opens slowly when the water pump is turned on; when the water pump is stopped, it can be closed in two stages of quick closing and slow closing, which can completely eliminate the water hammer.
【Product features】
1. It can replace the butterfly valve, gate valve, etc. at the outlet of the water pump, which is an integrated multi-purpose valve.
2. No vibration, no noise, stable performance, safe and reliable
3. Small body shape, light weight and simple structure
4. Good sealing effect, friction resistance and long applicable life
