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.

Table 2 provides ... pressure in the force mains. Valves can be used to stop and start flow, control the flow rate, divert the flow, prevent backflow, and control and relieve the
PVG 32 Proportional Valves Technical Information
www.imdl.gatech.eduThe LS pressure limiting valves save energy compared with the shock valves PVLP: • With PVLP all the oil flow to the working function will be led across the combined shock and suction valves to tank if the pressure exceeds the fixed setting. • With LS pressure limiting valves an oil flow of about 2 l/min [0.5 US gal/min] will be led

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.

ballots.api.orgPressure relief devices protect a vessel against overpressure only; they do not protect against structural failure when the vessel is exposed to extremely high temperatures such as during a fire. See API Std 521 for information about appropriate ways of reducing pressure and restricting heat input.
