Product DescriptionProduct Description25P Pilot-Operated Pressure Reducing ValveThe 25P series self-acting pilot-operated pressure reducing valve features an advanced external sensing tube design that continuously monitors downstream pressure fluctuations and intelligently adjusts the main valve opening to ensure stable output pressure. Even under no-load conditions, the valve reliably closes to precisely maintain the set pressure, delivering exceptional pressure stabilization performance.Key Advantages Precision Pressure RegulationIncorporates an oversized diaphragm with external sensing mechanism, demonstrating outstanding adaptability to primary-side pressure variations and secondary-side load changes, with control accuracy surpassing industry standards. Enhanced Durability Design? Single-seat main valve construction with specially treated hard alloy trim? Combined flat/tapered dual-sealing system? ANSI Class IV leakage complianceEnsures long-term sealing reliability Industrial-Grade ProtectionPrecisely reduces high-pressure steam to equipment's safe working range, effectively preventing pressure fluctuation-induced equipment damage - the ultimate safeguard for steam systems.Typical ApplicationsIdeal for applications requiring precise steam pressure control, includingPharmaceutical equipment ,Food processing ,Chemical production , Energy systems SpecificationStructural Features and ApplicationsThe 25P is a self-operated pilot-type pressure reducing valve that senses downstream pressure through an external pressure sensing tube, adjusts the main valve opening, and maintains stable pressure.Key Features:Maintains stable downstream pressure at set value, even with no downstream loadPilot-type design with single-seat main valveHard-alloy treated valve core for durabilityFlat and conical sealing methodsComplies with ANSI Class IV leakage standardLarge-area diaphragm with external detection mechanismExcellent stability with primary pressure fluctuationsHandles varying secondary-side loads effectivelyPerformance Benefits:Precise and reliable pressure reductionReduces high-pressure steam to safe working levelsProtects equipment from pressure-related damageProduct Configuration TableValve Body /Cover and upper/Lower discsGGG40Main Valve Seat Vale Core and Pilot Valve AssemblySUS420/440CPush rod, Main Valve SpringSS304/SS302DiaphragmQSN Aloy steeVSS316LSealing GasketGraphite Composite Gascket/Non-Asbestos GascketBody MaterialDuctile Cast IronBody Nominal Pressure &Max Operating Temp.Valve Body Nominal Pressure:PN16Ductile Cast Iron ≤232°CSize &ConnectionDN15-DN150 Flanged PN16/PN25DN15-DN150 Flanged ANSI 150Maximum Operating Pressure DifferencePressure Reducing Ratio 10:1Provided 3 different color springs to control downstream pressure:Yellow:0.2 bar g-2.1 bar gBlue:1.4 bar g-7.0 bar gRed:5.6 bar g-14.0 bar gDischarge Capacity ChartInstallation GuidelinesThis street light feature1.A steam separator should be installed upstream of the pressure reducing valve,and a drain valve should be installed at the bottom of the separator.2.A filter with a 100-mesh screen must be installed upstream.3.Bellows-sealed globe valves (full-bore type)should be installed both upstream and downstream of the PRV to ensure rated flow and proper control.4.Pressure gauges must be installed on both the inlet and outlet sides of the PRV.5.A bypass line should be installed for the PRV piping,allowing maintenance without system shutdown.6.The safety valve must be set to open below the downstream equipment's safe working pressure.During selection,consider the PRV's maximum flow rate,as its reseating characteristics and failure scenario must be accounted for.7.Pressure setting under no-load conditions:The distance from the PRV must be at least 3 meters;otherwise,excessive pressure fluctuations may cause temporary malfunction or significantly reduce the PRV's service life.ApplicationPackaging & ShippingCompany ProfileZhejiang Tai'an Valve Co., Ltd.
