The Spirax Sarco Process Controller Panel Kits are designed and built for multiple industry applications including Heating (HTG), Domestic Hot Water (DHW), Pressure, or Level control applications utilizing a variety of different modulating control valves and input sensors.
The BC3150 is a blowdown controller for steam boilers. It controls TDS (total dissolved solids – salts in solution) by opening and closing a blowdown valve.
The trap contains an inverted bucket mechanism which responds to the difference in density between steam and condensate. The discharge action is cyclic. Condensate and non-condensibles are discharged close to steam temperature. The SIB 45 is sealed for tamper-proof operation. The SIB 45/5 has an integral check valve.
The PP5 positioner is a single acting unit, requiring a 3 - 15 psi signal and is for use with linear pneumatic actuators. The positioner compares the output signal from a pneumatic controller (or transducer) with the valve position feedback, and varies the pneumatic output signal to the actuator accordingly.
The 25T is a self actuated pilot-operated temperature regulating valve. The temperature pilot has a calibrated dial for accurate temperature setting,
The 25PE has all of the features of the 25P, with the addition of an electric pilot. An electrical signal can override the pressure pilot. This valve meets Class IV shut-off specifications but is not suitable for dead-end service.
Normally closed, opens with temperature rise for cooling, single seat. Adjustable bleed 1/8” (Cv .44) provides bypass. (1” KX 51 only)
The trap contains a float valve mechanism which modulates to discharge condensate continuously at steam temperature, while non-condensible gases are released by a separate internal balanced pressure thermostatic air vent.
The 25 MT is a self-actuated temperature control valve with a calibrated dial for accurate temperature setting. A variety of solid-fill sensing bulbs are available (see TI-1-1123-US). The standard capillary tubing length is 8 feet, with an optional standard length of 15 feet.
The PP6 positioner can control any valve that is actuated by a linear or rotary pneumatic actuator that conforms with NAMUR. It guarantees an exact proportionality between the stroke of the valve and the value of the pneumatic input signal into the positioner.
