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.
Spirax Sarco Float Operated Liquid Drain Traps have a spherical stainless steel float which continuously adjusts the valve opening so that liquid is discharged at same rate as it enters the trap. The liquid level in the Drain Trap body is always above the valve seat, sealing the valve from gas leakage.
AEL7T series electric linear actuators are only suitable for the use on Spirax Sarco, Gestra and Hiter Valves.
The PN9000 series actuators are a compact range of linear actuators that are available in four sizes. This range of actuators comprise of four diaphragm sizes for matching the requirements of valves at various differential pressures. Each actuator has a mechanical travel indicator fitted and incorporates a fully-rolling diaphragm, except size 4, which provides good linearity over the operating stroke.
The PC3001, PC3000 and PC30 range of pipeline connectors are designed for use with two bolt universal swivel connector steam traps. Incorporating one integral piston stop valve, it is possible to isolate upstream of the steam trap.
