Product Directory - High Pressure Control Valves - Mark 708 Series
| Mark 708 Series Fractional Flow Control Valves A complete line with Cv values to 0.00001 (0,0000086 Kv), temperatures up to 1500°F (816°C) and pressures up to 5000 psi (345) bar. Our low flow range of products has been designed to handle the toughest micro-flow applications. |
| Mark 708MV Series Electronic Fractional Flow Control Valves Offers several advances including extreme accuracy, high turndown rations and repeatability. |
| Mark 708 Series Bellows Stem Seal Fractional Flow Control Valves Bellows stem seals eliminate fugitive emissions by surrounding the valve stem with a pressure-tight barrier, isolating the stem from the process fluid and preventing leakage to the atmosphere. |
| Mark 708 Series Cryogenic Bonnet Fractional Flow Control Valve Features a 9" bonnet extension that provides protection for the packing and actuator by preventing ice build-up, which can interfere with movement of the valve stem and affect valve performance. For cryogenic services with temperatures as low as -425°F (-254°C). |
| Mark 708 Series Double Packed Fractional Flow Control Valves An alternative to a bellows stem seal, and is used when standard packing will not adequately contain the controlled media. |
| Mark 708 Series with Finned Bonnet Fractional Flow Control Valve The cooling fin bonnet option is for the protection of the stem packing from elevated temperature associated with steam, hot water, and high temperature oil, gas, and liquid services. |
| Mark 709 Series Three Way Low Flow Control Valve A lightweight control valve for use as a mixing valve in low flow process applications. |
