Water Pressure Reducing Valves
media.wattswater.comPressure Reducing Automatic Control Valves • Size(s): 1 1⁄4" – 16" • Reduce high inlet pressure to constant, lower outlet pressure across a broad range of flow rates • Valves can be installed in parallel or series configurations for extended flow range or staged pressure reduction • Field-adjustable downstream pressure set point
Steam Pressure Reduction: Opportunities and Issues
www.nrel.govSteam pressure reduction affects mainly the high pressure part of the steam system. Within practical limits, pressure-reducing valves (PRVs) will adjust the pressure at lower levels to the previous set points. This means that most of the savings benefits from pressure reduction occurs in the high pressure section of the steam system. Summary. 1.
Vickers Pressure Relief Pressure Relief Valves
www.eaton.comValves Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to “vent” the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and reducing operating costs.
Head Pressure Control Valves - - Parker
sporlanonline.comThis backs liquid refrigerant up into the condenser reducing its capacity which in turn increases the condensing pressure. At the same time the hot gas raises liquid pressure in the receiver, allowing the system to operate normally. Sporlan has adjustable and fixed setting direct acting head pressure control valves for systems from 1 to 35 tons.
S 202 S200 Series Pressure Reducing Regulators
www.emerson.comThe quick-reacting S200 Series pressure reducing service regulator is typically used in an industrial or ... solenoid valves can cause sudden load changes. The resulting shock pressures and regulator instability can cause safety equipment to shut the installation down. But with an S200 Series regulator, transmission of shock

627 Series Pressure Reducing Regulators - Emerson
www.emerson.com627 Series Pressure Reducing Regulators W4793 Figure 1. Typical Type 627 Direct-Operated Pressure Reducing Regulator Introduction The 627 Series direct-operated pressure reducing regulators (Figure 1) are for low and high-pressure systems. These regulators can be used with natural gas, air or a variety of other gases. Performance
Pressure reducing valves - WATTS EUROPE
www.wattsindustries.comThe pressure reducing valves are completely automatic. WATER SAVINGS Water represents a major part of household budgets. Not wasting it makes for real savings, but do you know that 30% of water used in a house is heated. Less pressure means less water used, and therefore less energy consumed.
NEWCO Valves
www.newmansvalves.comNEWCO cast steel pressure seal gate valves are ideal for bi-directional flow and tight shutoff. Due to the flow characteristics of the wedge-to-seat design, gate valves should be operated in the full-open or full-closed position. Gate valves are utilized in applications where minimum pressure drop is desired. Globes Sizes: 2” to 24”
Pressure Relief and Regulating Valves
www.sunhydraulics.comPressure settings are insensitive to back pressure at port 2 up to 1000 psi (70 bar) maximum. Two Port Pilot Operated Soft Start Relief Valves – RP*T Sun’s unique soft start balanced poppet, two stage, relief valves ramp pressure up from a “threshold” pressure to the maximum set pressure over a fixed time period, which is slow enough to
