The product is composed of valve body, valve disc, valve stem and spring. It adopts clamp connection and has a compact structure. Due to the short closing stroke of the valve disc and the spring loading, the closing speed is fast, which can significantly reduce the water hammer phenomenon. The product has the characteristics of small volume, light weight, sensitive action, reliable sealing and convenient installation. It can be installed horizontally or vertically. It can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and other media.
