A. Easily Accessible Stem Packing: The stem packing can be adjusted without the need to remove the actuator, ensuring convenience and efficiency.

B. Seamless Actuator Mounting: Utilizing a one-piece, robust 17-4PH stainless steel construction across all sizes, along with a Double-D stem design and ISO 5211 top plate, enables direct mounting of actuators. This streamlined design reduces complexity in the setup.

C. Enhanced Stem Bearings: The upper stem bearing, crafted from a 316 stainless steel outer shell and TFE/glass liner, coupled with the lower stem bearing made of PSZ ceramic, offers exceptional resistance to corrosion and distortion caused by mechanical loading and high temperatures.

D. Blow Out Proof Stem: A retaining ring system is installed to ensure full retention of the stem in the unlikely event of internal stem failure.

E. Durable Ceramic Liner: Featuring a diamond-ground liner composed of Silicon Carbide Ceramic, boasting a high hardness rating. In most applications, this liner surpasses the durability of the hard-wearing single offset disc. This design ensures longevity with minimal maintenance costs, as only a few parts require servicing.

F. Tailored Control: As a control valve, tight shutoff is not provided by the disc. However, the disc design prioritizes maximizing flow with material options to minimize wear. Remarkably, this valve can swing through 360 degrees, providing versatility in operations.
