Swing Check Valve-Yuming Valve

Introduction

Structural advantages and features
1. The product is designed and manufactured according to the national standard GB/T12236, with reasonable structure and reliable sealing.
2. The sealing surface of the valve disc and the valve body is made of iron-based alloy or Stellite cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, corrosion-resistant, has good abrasion resistance and long service life.
3. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
4. The valve body material variety is complete, and the gasket can be reasonably selected according to the actual working conditions or user requirements, which can be applied to various pressure, temperature and medium conditions.
5. The valve disc rotates around the pin outside the valve seat to reduce the violent impact when closing.
6. The pin shaft and the valve disc are connected with an internal structure, there is no external leakage point, and it is more reliable to use.
