Low Flow Control Valves

LOW FLOW CONTROL VALVES The Jordan Valve Low Flow line is complete 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.

MK708 Low Flow Control Valves
The Mark 708 was developed by Jordan Valve to provide the most accurate control available for fractional flow services; whether for pilot plant installations, test stands, R & D facilities, or for specialized usage in processes such as dosing, injection and venting applications.

With Cv’s ranging from 0.00001 to 4.0 available in the 1/4" through 3/4" line sizes (0,000009 to 3,4 Kv in sizes DN8 through DN20), the Mark 708 offers design features that will provide enhanced performance to insure precision control on your most critical micro-flow flow applications.

MK708 Cryogenic Series Low Flow Control Valves
The Mark 708 for cryogenic service features a 9” bonnet extension that provides protection for he 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).

MK708 Finned Bonnet Low Flow Control Valve
The cooling fin bonnet is for the protection of the stem packing from elevated temperature associated with steam, hot water, and high temperature oil, gas, and liquid services. The finned bonnet cools the area around the packing, which permits the use of standard packing materials that otherwise would not be suitable for the service temperature conditions. For steam, hot water, and high temperature oil, gas and liquid services up to 1500°F (815°C)

MK708 Bellows Seal Low 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. For an extra measure of protection, the bellows stem seal option provides a back-up seal of Teflon, braided or Graphite/Grafoil packing along with a detection port for use in monitoring potential emissions leakage.

MK709 3-Way Low Flow Control Valves
The Mark 709 is a lightweight control valve for use as a mixing valve in low flow process applications. Featuring a three-way body design, it is constructed with two inlets to blend two separate flow streams into a common outlet, creating a third fluid. With multiple spring actuators in a choice of sizes for differential pressures up to 1460 psi (100 bar)
