The PP6 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 pneumatic input signal into the positioner. The PP6 has a cast aluminium housing that is also treated for outdoor installation.
The Spirax Sarco removable Acoustic Blanket is an easy to install, reusable, one-piece asbestos free encapsulation designed specifically to fit and be used on Spirax Sarco 25 series main valves and L and K series control valves.
The trap contains a float valve mechanism which modulates to discharge condensate continuously at steam temperature. Non-condensible gases are released by a separate internal balanced pressure thermostatic air vent.
The DC Series are type diaphragm pneumatic actuators used to operate linear displacement valves in modular or block control system. It is a versatile equipment which makes possible the change of direct acting for inverse acting, with no need of additional parts.
A range of forged carbon steel compact manifolds with integral piston type stop valves for steam distribution and condensate collection duty. MSC manifolds can be used for either steam distribution duty or condensate collection duty depending on the way they are installed.
Line size separator & associated trap kit (Mod S1, S2 or S3). 3A certified steam filter (Mod CSF16 w/ 5 micron element). Pressure gauge assemblies up & downstream of the filter to provide visual indication of when elements need to be cleaned & replaced. Sample cooler for sampling steam downstream of the filter. Stainless steel pipe downstream of the filter. Sanitary check valve and sanitary components downstream. Isolation valves at key points to enable ease of maintenance of the separator, trap, and steam filter.
The 25 MT is best installed in a horizontal line with the adjustment knob at the top. A strainer before the valve will protect it from line dirt. Fit the strainer on its side and insure adequate clearance for screen removal.
The Spirax Sarco 3" (DN80) and 4" (DN100) FT450 is a high capacity Float & Thermostatic steam trap. The float adjusts the position of the double seated main valve so that condensate is discharged continuously at the same rate as it enters the trap.
Cv calculation is an interactive process requiring knowledge of valve dynamics, piping geometry factors, and outlet velocities. In practice, this sizing chart is based on emperical values and will cater for most applications.
Types SRV461/463 Direct Acting Pressure Reducing Valve with nonrising adjustment screw, O-ring soft seal on valve plug for tight ANSI Class VI shutoff, and 316 Ti stainless steel construction for wetted parts.
