(24) 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.

(72) 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.
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).
The MK708 Double Packed is an alternative to a bellows stem seal, and is used when standard packing will not adequately contain the controlled media.
The optional bonnet features a double packing arrangement separated by a lantern ring. With a double packed bonnet, lubricant is pumped into the packing sets, supplying a tight seal similar to that provided by a bellows stem seal.
The double packed bonnet is an excellent choice when service conditions could cause damage to a bellows assembly.
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. 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.
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.
(40) The Jordan JPR and JHR pressure reducing regulators are designed for gas or liquid service and with inlet pressures up to 3600 psi (248 bar). Standard adjuststable outlet ranges are from 1 - 10 psig (0.07 - 0.69 Barg) thru 10 - 750 psig (0.69 - 51.7 Barg). The JPR/JHR Series can be manufactured from various barstock materials, and is ideally suited for either corrosive or non-corrosive services.
The JPR/JHR Series is ideally suited for the following applications: corrosive gases, sampling systems, chemical/petrochemical plants, instrumentation systems, research facilities, and chromotography.
The Jordan JHP is designed for gases and liquids with inlet pressure to 3600 psig (248 Barg). Standard adjustable outlet ranges from 50 - 1500 psig (3.4 - 103 Barg). Flow coefficient of 0.06. This general purpose use regulator can be ordered with a variety of options to meet
your system demands.
(32) The Jordan JBP back pressure regulator is designed for gas or liquid service up to 750 psig (52.0 bar). Flow coefficients are available in 0.10, 0.20 and 0.30. The back pressure regulator controls the inlet pressure. It is used to maintain a pressure in a process, or act in a relief valve capacity. It can be manufactured in a variety of barstock materials, and is ideally suited for either corrosive or non-corrosive services. Standard construction
includes machined aluminum knob with anodized finish, diffusion resistant stainless steel diaphragm.
The JBP is ideally suited for the following applications: manufacturing, research facilities, sampling systems, pump bypass, analyzer back pressure and economizer circuit.
(30) The Jordan JCYL Cylinder Pressure Regulator and JYCL-2 Two Stage Cylinder Pressure Regulator are designed for gas or liquid service with inlet pressures up to 3600 psig (248 Barg). Standard adjustment outlet ranges from 1 - 10 psig (0.07 - 0.69 Barg) thru 10 - 750 psig (0.69 -51.7 Barg). The JCYL Series is designed to handle fluctuations in supply pressure while maintaining precise, accurate outlet pressure control. Manufactured
from a variety of barstock, it is ideal for corrosive and non-corrosive gas services. Standard construction includes 40 micron integral filter, machined aluminum knob with anodized finish, and diffusion resistant stainless steel diaphragm. Gauges and CGA fitting are optional.
