1.Outside screw & yoke design. The stem extends out of the bonnet, the open/closed status can be observed directly, convenient for on-site operation and maintenance.

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

3.Metal hard sealing structure features high temperature resistance and erosion resistance, suitable for high-temperature medium with tiny solid particles, stable long-term pressure bearing.

4.Straight-through flow passage brings minimum flow resistance and low pressure loss, ideal for on-off control of large-diameter main pipelines.

5.Wedge single gate structure ensures uniform contact of sealing faces upon closing, reliable tightness and stable operating torque.

6.Standard RF flanged ends match standard industrial pipeline flanges for easy installation, suitable for horizontal and vertical piping layout.

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

8.Optional material 316L, WC6; bevel gear, electric and pneumatic actuators can be equipped to realize remote control.
