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.
NS Normally open, closes with temperature rise for heating, double seat. NSRA Normally closed, opens with rising temperature for cooling, double seat.
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 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 1000 Control Series which is considered a high quality globe valve providing excellent sensitivity, fine con- trol and easy adjustment.
The Spirax Sarco LC2200 is used to control an electrically actuated valve in response to a signal from a capacitance probe, providing proportional modulating control of liquid levels. It can be used for level control of boilers, deaerators, and tanks.
EL3500 series electric linear actuators are for use with KE and LE two port valves (DN15 to 50), Self-acting valves (BX, SB, KA, KB, KC and NS) and TW three port valves. This range offers actuators for on /off control, modulating control with external valve motor drive switches and modulating control with 0-10 or 2-10 Vdc input signal.
