SP7-10, SP7-11 and SP7-12 Smart Positioners

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°.

Cast Steel Float and Thermostatic Steam Trap FT450

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 balanced pressure thermostatic air vent.

Pilot Operated Temperature Regulators 6" 25T

The 25T is a self actuated pilot-operated temperature regulating valve. The temperature pilot has a calibrated dial for accurate temperature setting, and is available with a variety of solid-fill sensing bulbs.

Air Eliminators 13WS WHS

13WS and 13WHS Air Eliminators improve the circulation of pressurized liquids by eliminating air and other non-condensible gases which may collect at high points in the system. The EPDM valve head ensures tight shut-off.

Type 25P, 25PA, 26P and 26PA Pressure Reducing Valves

1000 Series Classes 150 to 600 ANSI

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.

6A Air Vent

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.

DP143, DP143G, DP143H

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.

LSB31, LSB32, LSB33, LSB34, LSB71, LSB72, LSB73 and LSB74 Limit Switch Boxes for BVA300 Series Actuators

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.

Float and Thermostatic Steam Traps FT FTB FTI OK FTS150 FTS300

Spirax Sarco Float & Thermostatic Steam Traps are ideally suited for most HVAC and process applications. The spherical stainless steel float automatically adjusts the position of the main valve so that condensate is discharged continuously at the same rate as it enters the trap.
