Installation and Maintenance Instructions
The SX80 controller is a 1/16 DIN panel mounted unit, suitable for single and multiple set point applications utilising the Spirax Sarco range of pneumatic or electric control valves and electrical and electropneumatic instruments.
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.
The trap contains a float valve mechanism which modulates to discharge condensate continuously at steam temperature. Noncondensible gases are released by a separate internal balanced pressure thermostatic air vent.
The BC3200 and BC3210 are dual voltage controllers which monitor the conductivity of liquids, and are used with a boiler blowdown valve or condensate dump valve to monitor and control TDS levels.
The DC Series are type diaphragm pneumatic actuators are used to operate linear displacement valves in modulating or block control systems.
The Stonel Limit Switch is for use with the K Series pneumatic control valves and PN5000/6000 actuators. It is mounted on the PN5000/6000 actuators and can provide visual indication if the valve is fully open, fully closed, partially open (0-100%) or partially closed (0-100%). By comparing flow rates over time with your valve position, you can determine valve wear.
The SP7-1* smart 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 electrical input signal (mA) into the positioner. The SP7-1* has a cast aluminium housing that is also treated for outdoor installation. The unit can be mounted onto pneumatic actuators either rotary -57 to 57° or linear -28 to 28°.
