Product Advantages

1. Outside Screw & Yoke (OS&Y) design. The stem extends out of bonnet, opening and closing position can be observed directly, convenient for field inspection.

2. CF8 304 stainless steel body features excellent corrosion resistance, suitable for weak acid, weak alkali, humid and corrosive media, widely applied in high-pressure pipelines of chemical, oil & gas, energy and water treatment industry.

3. Metal hard sealing pair owns high temperature resistance, erosion resistance and anti-cavitation performance, stable sealing performance under long-term high temperature and high pressure service.

4. Straight-through flow passage brings minimum flow resistance, smooth medium flow and low pressure loss, ideal for on-off cut-off of high-pressure main pipelines.

5. Wedge single gate structure ensures uniform fitting of sealing surfaces during operation with stable torque, high pressure bearing capacity to meet PN100 high-pressure working condition.

6. High-pressure standard RF flanged ends comply with high-pressure piping specification on flange thickness and bolt size, firm installation, available for horizontal and vertical piping layout.

7. 100% hydrostatic shell strength test & tightness test before delivery; PT/UT NDT inspection for castings is available.

8. Custom material options including 316L, duplex stainless steel; bevel gear, electric and pneumatic actuators are optional to realize remote automatic control.
