Product Description

H71X pumpkin type check valve Overview:
Series of clamp type silent check valve is the use of internal pressure changes in the pipeline, internal pressure self-driven check valve. The product valve disc movement automatic guidance, open and close flexible, free movement, good sealing performance, small shape structure size light weight, easy disassembly, low noise, vertical, horizontal installation can be.
The clamp lift check valve can be installed on the pump outlet pipeline, which is mostly used when the pump stops, to prevent the pipeline with pressurized water flow back impact the pump to ensure safety.
H71X pumpkin type check valve installation instructions:
1, before installation, please check whether the valve's caliber, pressure level and appearance are intact. Press the valve shaft by hand whether the action is flexible or unimpeded.
2. Check whether the red arrow marked on the valve body is consistent with the pipeline water flow direction.
3, when clamping the valve, the bolts tighten the force balance, so that the valve force is consistent, and the clamping force is not too large.
