The Spirax Sarco LC2400 is used to connect a level controller to the 4- 20 mA output signals from the steam flowmeter and (where fitted), the water flowmeter. The controller can be an LC2200 (for an electrically actuated feed valve), or an LC2300 (for a pneumatically actuated valve).
The PP Series is a linear pneumatic piston type actuator used on linear valves in module control system. It is a versatile actuator which can be changed from direct acting to reverse acting, with no need of additional parts.
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 thermostatic air vent.
The BRV2 is a direct acting pressure reducing valve suitable for steam or gases, such as compressed air.
The 25E is controlled by an electric pilot valve. The main valve opens wide when the pilot is energized; it closes tight when the pilot is de-energized. The 25E does not modulate or throttle steam at part load.
The 1000 Series is a globe valve considered a high quality valve providing excellent sensibility, fine control and easy adjustment, with very reduced weight and size.
The 6A Air Vent has both a float and a thermostatic bellows for use where air, condensate and steam may be present (as in one pipe steam heating systems.) The 6A will discharge air, while preventing the escape of either condensate or steam. An outlet check valve prevents the re-entry of air.
These instructions relate to the use of the DP143 (Section 2.1) and DP163 (Section 2.2) pilot operated pressure reducing valves on steam applications but can be used as a guide when the valve is used on compressed air applications. The DP143G and DP163G are recommended for compressed air applications, both having a nitrile seal for the main valve and pilot valve assemblies.
LSB limit switch boxes are normally used for indicating valve open or valve closed position. They also allow switching points to be adjustable over the full range of actuators. There is an open/ closed valve position indicator mounted at the end of the switch box axis, at the top of the cover. LSB's include a stainless steel linkage kit for direct mounting to BVA300 series actuators.
