The EP6 is a 2 wire loop powered positioner requiring a 4-20 mA control signal, and is designed for use with linear and rotary pneumatic valve actuators. The positioner compares the electrical signal from a controller with the actual valve position and varies a pneumatic output signal to the actuator accordingly.
With the highest precision the EP500 electropneumatic positioner can control any valve that is actuated by a linear pneumatic actuator that conforms with NAMUR. It guarantees an exact proportionality between the stroke of the valve and the value of the electrical input signal (mA) into the positioner.
The 26P, 26PA, 26PE and 26BP self-actuated pilot-operated pressure regulator have been manufactured using cast iron.
Whatever the reason for reducing or maintaining pressure, proper control at any time demands an automatic valve that can reduce or maintain steam pressure accurately, reliably and economically.
In sanitary manufacturing applications that employ the use of fluid systems, such as in the pharmaceutical industry, regulating fluid flow and pressure is essential to maintaining high product and production quality.
The 25E is controlled by an electric pilot valve. The main valve opens wide when the pilot is energized; it closes when the pilot is de-energized. The 25E does not modulate or throttle steam at part load. This valve meets Class IV shut-off specifications but is not suitable for deadend service.
The AEL8 Series linear electric actuators are a cost effective range of linear electric process actuators, with diagnostics, only suitable for the modulation of Spirax Sarco Group valves.
The EP6 Electro-pneumatic positioner can control any valve that is actuated by a linear pneumatic actuator that conforms with NAMUR. It guarantees an exact proportionality between the stroke of the valve and the value of the electrical input signal (mA) into the positioner.
The BC3250 is a blowdown controller for steam boilers. It controls TDS (total dissolved solids – salts in solution) by opening and closing a blowdown valve. It also controls a bottom blowdown valve, which removes precipitated solids from the bottom of the boiler shell.
