The HCV valve (HEMI cartridge valve) is an innovative design that incorporates many positive features from other valve types. These features are combined into a single product platform that is UNIQUE to the Chromatic HCV product line and not found in any other valve on the market. The HCV is highly adaptive to a variety of process applications from low to high temperatures; clean to dirty service; and on-off to control.
The DOV valve (Double Offset Valve) extends the technology from the HCV and delivers a rotary valve with dual mechanical wedge seals. The standard DOV is a trunnion mounted design that provides a Double Isolation and Bleed without the use of seat springs or line pressure to ensure a bubble tight seal. The DOV maintains the UNIQUE top entry cartridge style for easier maintenance and fewer leak paths. The operation of a DOV is 1/4 turn that allows for more cost effective actuation and lower fugitive emissions. A wide variety of options enable the DOV to include high temperature seals, corrosion resistant coatings, live loaded stem packing and alloy materials.
The EBV valve (Extended Body Valve) is a simple and innovative extension of the HCV. The EBV was designed specifically for buried valve applications with above ground maintenance in mind. The UNIQUE cartridge design enables the entire trim of the valve to be assembled at one time allowing the body to remain in line during periods of maintenance. The body extension is a single section of pipe welded between the top of the valve body and top bonnet. The pipe section is rated and pressure tested to the same parameters as the valve body. The EBV can be supplied as a double block and bleed without the need for sub-surface bleed connections. The EBV is an excellent option for buried drain valves, buried manifolds, buried pump control valves and has been manufactured with extensions up to 10 feet.
The Chromatic FCV valve (Flow Control Valve) is an engineered rotary control valve that can be applied to a variety of flow and pressure control applications. The FCV can be applied in gas, liquid and slurry control valve duties. The FCV HEMI can be designed with a specific port opening based on the customers flow conditions. Port designs are readily available in 30-60-90 degree V-port and characterized trim for specific conditions. Options are available for anti-cavitation and severe service.
