The Spirax Sarco acoustic silencer is designed to attenuate noise generated by control valves and/or pilot operated regulators. The silencers are particularly effective in limiting the propagation of valve generated noise into the downstream piping. Upon flow and piping configuration, noise attenuation of up to 35 dBa can be expected.
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 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 EP6 Electro-pneumatic 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 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 25BP Back Pressure Regulator maintains a constant upstream pressure in a piping system. The reverse-acting pressure pilot opens the main valve when the sensed upstream pressure increases.
