Series 2000 Angle Seat Control Valve (on/off)
Series 2000 is one of Burkert’s extensive range of general purpose Control Valves. The standard valve and actuator is suitable for on/off duty but it can be fitted with other control heads and parabolic plug so that it can function as a modulating control valve. This valve is an angle-seat design and is operated by a single or double acting pneumatic actuator (either PA or PPS material, depending on ambient temperature) which is rotatable and with visual indicator. Valve is 2-way, normally closed and is available in sizes 3/8” (Kv3.7) → 2 ½” (Kv90) with threaded ends female BSP.
Body materials: Gunmetal or 316L
Seal material is PTFE (NBR, FKM, EPDM on request).
Can be ordered with flow direction above (gas & steam) or below the seat (liquids).
Series 2012 is the flanged version of the same valve
Options: Different Control Heads (8691, 8690, 1062), banjo pilot valve, actuator for high ambient temperature, normally open valve (see data sheet for all options)

Series 2301 Globe Style Control Valve (modulating)
Series 2301 is a globe style control valve for modulating service which can be operated by a single or double acting actuator. It can be fitted with top control electro-pneumatic positioned or process controller. Valve is 2-way, normally closed and is available in sizes ½” (Kv0.5) → 2” (Kv27.9) with ends flanged Ansi 150#.
Body material: 316L
Seal material is PTFE/St. Steel or St. Steel / St. Steel
Can be ordered with flow direction above (gas & steam) or below the seat (liquids).
Valve operating pressures: to 16 bar (depends on trim/actuator
Max. pilot pressure : 5.5 -7 bar
Options: Different Control Heads (8692, 8693, 8694,8696), "Element" continuous control (model 8802-GD), equal % seats, normally open valve (see data sheet for all options)

Model 4370 Pneumatic Control Valve (BZ/DI/WCB/316SS)
Model 4370 is the Australian made version of US manufactured Mk70, diaphragm operated Control Valve. The valve is metal/metal seated (Ansi class IV) and utilises the same sliding gate seats found in Jordan’s range of Pressure Regulators (4350/4360) and Temperature Control Valves (4380). It is available in sizes ½”→ 2” (Cv 2.5 to 30). The standard valve has threaded (bspt) ends but can be flanged on request. The valve is actioned by a multi-spring pneumatic actuator and can be used for on/off or modulating for liquids, gases, chemicals and steam. Flow is controlled by the movement of the gate/disc which moves in response to a 3-15 psi pneumatic signal received from a controller. Where the signal is in milliamps, an I/P transducer can be fitted (i.e. converts a 4-20mA signal to 3-15 psi) or, for even more precise control, the pneumatic actuator can be fitted with a pneumatic or I/P positioner.
Maximum inlet pressure- BZ (2100kpa) / DI (3,100kpa) / 316SS (4,500kpa)
Maximum temp- BZ/DI (260°C)/ 316SS (343°C)
Max pressure differential: 125-250 psi (without positioner), 125-550 psi with positioner
Options: 43701 Cv 50 High Flow version, equal % seats, low flow seats for all sizes, side or top mounted positioner, flanges to AS or Ansi. Many more options, higher pressure/temps etc for US made Mk70 (see download), flanged MK711

MK708 / MK8000 Low Flow Pneumatic Control Valve (WCB/316SS/Monel/Alloy 20)
Jordan MK708 and MK8000 are globe style, low flow, pneumatic control valves, either cast or machined from barstock. They are operated by a multi-spring pneumatic actuator. Top or side mounted positioners are fitted where greater accuracy is required or where high pressure differentials occur. Many combinations of body/trim material available, hard or soft seat (for MK708 when zero seat leakage required)
Mk 708 - ¼”→ ¾” (Cv’s 00001 to 4.0), class IV or VI shut-off, max WP & DP 5,000 psi
Mk 8000 - ½”→ 2” (Cv’s 0.05 to 16.0) class III or IV shut-off, WP to 6,000 psi (414 Bar), Max differential Pressure to 5,000 psi
Options: Mk8000 is avail in almost any exotic material, including PVC and Kynar, also 3-way version
