Check valve
H77 Clamp Butterfly check valve
H77 Clamp Butterfly check valve. The structure length is short, its structure length is only 1/4 to 1/8 of the traditional flange check valve.
Specifications
- Structural form
- Type H77 Clamp double flap swing check valve
- Water hammer pressure
- Small, short disc stroke, and spring assisted closing, closing speed fast
- Size and weight
- The structure is very short in length, small in size and light in weight, which brings great convenience to the installation,handling, storage and pipeline layout of the valve, and can save a lot of m
- Fluid resistance
- Small, the fluid resistance coefficient is 2.6~2.7, with the increase of valve diameter, the fluid resistance coefficient decreases
- Install
- Can be installed horizontally or vertically, light weight, no need to set a support for the valve
- Opening pressure
- Very small, the disc can be fully opened at a small pressure difference
- Reliability
- The valve is the whole structure, simple and compact, the impact force is small when the valve is closed, the water hammer pressure is small, the valve life is long and the reliability is high
