Pressure Regulating (Reducing) Valves. SR 50 Series Pressure Regulating (Reducing) Valves maintain a set downstream pressure independently of a higher pressure upstream. As the upstream pressure increases to the set pressure, the valve closes; it opens when the downstream pressure falls below the set pressure. The SR 50 valves are sensitive and provide precise control, protecting items from damaging pressure surges.

Air Release (Venting) Valves AR Series Air Release (venting) Valve allow gases to escape from un pressurized pipe lines. As the un pressurized air vents, liquid rises to the float (an inverted cup), which lifts the float up against the seat, holding liquid pressure. The float will not release until the pressure on the inlet side of the valve is equal to the outlet pressure of the valve (normally atmospheric).

Variable Area Flow Meters. Ideal for plastic piping systems, they provide a combination of accurate flow measurement and clear flow indication from a distance.The units must be installed vertically with the flow upwards. Tube materials are available in clear PVC, Polyamide(PA), Polysulfone(PSU) and PVDF. The flow meters are accurate to ±3% of indicated value and ±1% of full scale

Gauge Isolators SG Series Gauge Isolators allow inexpensive pressure gauges, or any other pressure instrument to be used in corrosive services. The upper chamber (gauge side) is filled with a stable fluid such as glycerine‡. A diaphragm separates it from the lower chamber which receives the media under pressure.
The 1/2" gauge connection allows use of the popular 4" and 4-1/2" diameter gauges. Pressure switches or transmitters may also be installed. Customers can easily fill isolators and install their own gauges.
