1.Swing type structure with smooth flow passage and low flow resistance, suitable for medium transportation in large-diameter pipelines. Equipped with hydraulic actuator to assist opening and closing actively and suppress water hammer.

2.CF8 (304 stainless steel) body resists weak acid, weak alkali, moisture and corrosive media, widely used in chemical industry, water treatment, energy, pump station and other industrial pipelines.

3.Metal hard sealing structure features high temperature resistance and erosion resistance, applicable for high-temperature media with tiny solid particles, providing long-term stable tightness.

4.Matching hydraulic cylinder enables controllable valve closing, effectively restraining pipeline water hammer and protecting downstream equipment such as pumps and pipelines.

5.Swing disc operates smoothly with small opening/closing impact. Standard RF flanged ends match standard industrial pipeline flanges, suitable for horizontal pipeline installation.

6.High-rigidity integral structure, bolted bonnet design facilitates internal maintenance and replacement of sealing components.

7.100% hydrostatic shell strength test & tightness test before delivery; PT/UT NDT inspection for castings available.

8.Optional materials: 316L, WCB; hydraulic control system and position feedback device can be equipped for automatic pump station systems.
