Xomox®XLC fully-lined ball check valves offer economical solutions for the vast majority of chemical applications with a unique flexible seat that enables Class A and API-598 sealing, a first for lined ball check valves. Critical equipment is protected from cross contamination and the effects of backflow, even in the horizontal position where the XLC’s angled ribs guide the ball tightly into the seat. With metal-to-metal contact at the joint seal and wide conical plastic connection, the risk of dangerous external leaks is drastically reduced by the Xomox®XLC.

Conval, a global leader in high-performance valves for the world's most demanding applications, offers Clampseal® Cryogenic Valves for high-pressure, low-temperature applications to -420F. This is below the temperature at which nitrogen liquifies, and the temperature used in many cryogenic processes in liquefied natural gas (LNG), manufacturing, heat treating and vaporizing.
Clampseal Cryogenic Valves are available in 1/2" through 4" sizes with socket weld, butt weld or special ends. Pressure ratings include ASME class through 2500#, ASME B31.3, ASME B16.34, and MSS SP-84. Standard materials include forged stainless steel, SA 182 and F316. Special pressure classes and materials are available. Features include metal-to-metal pressure seal bonnet; solid Stellite seating surfaces; single-piece gland; in-line servicing; and two-year warranty.

Conval offers Clampseal® fire-safe globe valves for refining and chemical plants where fire safety is a major concern. The fire-safe valves are available in Y, angle and T-pattern configurations in ½” through 4” sizes, up to ASME 2500 pressure ratings, and with NPT, butt weld, or socket weld ends. Other end connections are available upon request.
The Clampseal fire-safe valve contains a simple mechanism that compensates for thermal expansion. As a result of this and other design features, the valve meets API fire-safe standards by extremely high margins. The testing procedure calls for the test valve to be placed in-line and pressurized for 75% of rated pressure, then subjected to a 1,400 – 1,800° fire for 30 minutes. The valve is then quenched with water to cool it to ambient temperature, cycled to prove operability, then subjected to further testing. The valve is required to maintain strict leakage allowances during and after the burn.

Val-Matic Valve & Mfg. Corp. now offers Air Valve “SuperValves” with Ductile Iron Bodies and Covers as the standard. The SuperValves are premium water and wastewater air valves offered with premium features with availability from stock. Clean water air valves use EPDM seating material and wastewater air valves use Buna-N material. SuperValves are holiday tested and include stainless bolts and stainless steel plugs on the clean water valves. All valves are coated with a non-stick fusion-bonded epoxy (FBE) internally and externally, which is the perfect solution for severe applications such as those of a WWTP and is able to withstand the harsh wastewater applications, thus reducing the frequency of maintenance.
