The Series 400 Hard Seat Valves, specifically the 402 MFC model from Clark Solutions, are designed for high-pressure applications with a maximum pressure rating of 10,000 psi at 200¬8F. These valves feature a metal-to-metal hard seat design that has been 100% helium leak tested to ensure reliability. The construction includes a blow-out proof stem that provides a secondary seal when fully open, and the stem packing is located below the threads to prevent thread galling and corrosion. The 402 MFC model utilizes Viton O-rings and Teflon back-up rings for effective sealing. It has a standard orifice size of 0.187 inches and a flow coefficient of 0.44, making it suitable for precise flow control. The valve's stem and bonnet threads are rolled for enhanced strength and smoother operation, and it includes a bonnet lock pin to prevent accidental loosening. The valves are available in steel or 316 stainless steel, with finishes that include electroless nickel plating for carbon steel and electropolishing for stainless steel. Optional panel mount bonnets and panel nuts are also available.
