The EL-PRESS series digital electronic Pressure Meters and Controllers have a well-proven compact thru-flow design and are available in pressure ranges from 2-100 mbar up to 8-400 bar, both in absolute and relative (gauge) pressure. A differential pressure transducer can also be supplied in the ranges of 2-100 mbar up to 0,3-15 bar. The pressure controller performs with high accuracy and repeatability and should be specified for forward or backward pressure control. Todays EL-PRESS series are equipped with a diaphragm type piezoresistive pressure sensor and a digital pc-board as standard and offer high accuracy, stability and reliability. The basic digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output, the instruments also offer analog I/O. As an option, an integrated interface board provides DeviceNet, PROFIBUS-DP, Modbus-RTU or
FLOW-BUS protocols.

The Type-700BP Back Pressure Regulator is a high flow, highly accurate pneumatic relief valve with an adjustable set point. It's primary function is to provide protection against over pressurization in the downstream portion of a pneumatic system. This precision unit is capable of handling flows up to 50 SCFM. A rolling diaphragm provides the sensitivity that causes the Type-700BP to vent to atmosphere in response to the slightest upstream changes.

Back Pressure Valves
* CNC precision machined parts
* Cost effective and reliable
* Pressures from 8-150 psi (350 optional)
* Variety of materials available
* Anti-syphon protection
* Fine pressure adjustment
* Optional air release and gauge port
Sigmamotor back pressure valves prevent siphoning and varying rates of dosage from fluctuating downstream pressure by enacting positive discharge pressure in your metering pump system.
Inside the valve is a diaphragm held in place by a spring which is pressure set. When the pressure is exceeded the PTFE diaphragm is pushed up and material flows through the valve to the injection point. The valves are set at 50psi but are easily adjusted in the field.

The Type-9OOX l/P, E/P transducers are a series of compact electronic pressure regulators that convert an electrical signal (current or voltage) to a proportional pneumatic output. Utilizing internal solid-state feedback circuitry, the Type-9OOX provides precise, stable pressure outputs to final control elements. Immunity to the effects of vibration or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for use in demanding applications.
The heart of this unique technology is a bimorph piezo actuator that is encapsulated in a protective skin. This protective skin provides defense against the humidity and contaminants often found in process operating environments.

APPLICATION:
To control the flow of Water, Air, Gas, Solvents, Vacuum and any other fluids not reactive with construction materials and free of sediment. Buna N seating of the pilot and main orifices make the valves ideal for TIGHT SEATING, LOW PRESSURE and LOW FLOW conditions. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
OPERATION:
Valve closes when energized and opens when de-energized. When the coil is energized the plunger presses the poppet, closing the pilot orifice, and opens a bleed passageway to permit pressure to build above the piston and seat it. Upon de-energizing the coil, the pilot orifice is opened, relieving the pressure above the piston allowing it to leave its seat. The bottom spring allows the valve to operate at zero pressure drop.
