Thermostatic steam air vents sense the temperature difference between steam and non-condensible vapors to operate a valve head. The vent is wide open when cold providing a free access for non-condensibles and air to be removed from the system.
EL5600 series electric linear actuators are for use with LE and KE two port valves, QL three port valves and all bellows sealed options. Actuators will normally be supplied fitted to the control valve. When supplied separately, ensure the actuator selected is capable of giving the force necessary to close the two port or three port valve against the expected differential pressure.
The Spirax Sarco LC2300 is used to control the positioner of a pneumatic valve in response to a signal from a capacitance probe, providing proportional modulating control of liquid levels.
The PP6 is a pneumatic positioner requiring a 0.2 to 1 bar control signal, and is designed for use with linear and rotary pneumatic valve actuators. The positioner compares the pneumatic signal from a controller with the actual valve position and varies a pneumatic output signal to the actuator accordingly.
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 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.
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 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.
The SIB45 is an all stainless steel sealed inverted bucket steam trap. It is provided with pressure change assemblies for pressure differentials between 0.5 and 45 bar. Traps for 45 bar are provided with an in-built check valve as standard.
The AEL7 Series linear electric actuators are a cost effective heavy duty range of linear electric actuators only suitable for the modulation of Spirax Sarco Group valves.
