Product Description

Waits Valve's pneumatic wafer soft seated butterfly valve has made adjustments to the design from the performance aspect. Through careful design, research and development and manufacturing, it provides customers in the global market with better products and usage experience.

1. Use highly elastic valve seat rubber

The rubber content of the EPDM valve seat is 50%, and we simulate more than 10,000 opening and closing tests to ensure the stability of the sealing performance and no leakage.

The main related properties of this valve are as follows: Shore A hardness/degree 72±3, 200% tensile stress/Mpa≥6, tensile strength Mpa≥15, elongation at break/%≥350, permanent deformation at break/%≦10, tear strength/KN.m-1≥35, compression permanent deformation (70℃*22h, compression rate 25%)/%≦20.

In addition, the valve seat is designed as a wide edge. Compared with the narrow edge valve seat, the wide edge valve seat has a wider contact surface with the pipeline flange, and the diameter can reach almost 20mm, which has better sealing performance.

2. The butterfly plate and valve shaft are connected without pins, which will not cause leakage and corrosion due to the installation of pins. In addition, the method of disassembling the valve shaft is very simple, which makes it easy to replace the valve seat.

3. The valve body is equipped with an anti-scattering device, which is safer to use in the pipeline.

Performance Features

1. Pneumatic wafer soft seated butterfly valve is a small, lightweight valve that is easy to disassemble and repair.

2. The valve structure is simple in design and compact as a whole. The opening and closing speed during operation can reach 90.

3. During operation, the torque is small and more labor-saving.

4. In terms of the important sealing performance of the valve, we conduct strict gas tests to achieve zero leakage.

5. As a professional manufacturer, we consider the customized needs of customers. Pneumatic wafer soft seated butterfly valve can choose different component materials and is suitable for a variety of media with a wide range of applications.

6. The flow characteristics tend to be linear and the adjustment performance is good.

7. Through testing, the product can be opened and closed for tens of thousands of times and has a long service life.
