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 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 Spirax Sarco S20 sensor chamber is fitted with conductivity and temperature sensors used to determine the conductivity of liquids. The use of a temperature sensor enables an accurate measurement to be made when the temperature varies, as in the case of condensate return monitoring systems.
From the inlet pressure, back pressure and filling head conditions given below, select the pump size and check valve package which meets the capacity requirement of the application.
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.
The Drip Pan Elbow is to be connected to the discharge connection of the Safety/Relief Valve by a short pipe nipple. Flanged valves 4” and smaller will require a companion flange and short nipple the same size as the valve outlet. The drain connection on the bottom of the elbow should be piped to waste.
Installation and Maintenance Instructions
The Spirax Sarco 600 and 900 series alloy steel inverted bucket steam traps are designed for installation in vertical pipework between flanges. They are suitable for a wide range of pressures and applications and include an integral check valve on the inlet.
The type MSC forged steel manifolds centralize steam distribution and condensate collection for up to 12 sources. Both models have integral piston valves with a variety of connections, making them particularly well suited for tracing applications.
