Product Description

Product Description

25P Pilot-Operated Pressure Reducing Valve

The 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 Regulation
Incorporates 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 compliance
Ensures long-term sealing reliability

 Industrial-Grade Protection
Precisely reduces high-pressure steam to equipment's safe working range, effectively preventing pressure fluctuation-induced equipment damage - the ultimate safeguard for steam systems.

Typical Applications
Ideal for applications requiring precise steam pressure control, including
Pharmaceutical equipment ,Food processing ,

Chemical production , Energy systems

 
 
 
 
 

Specification

Structural Features and Applications

The 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 load
Pilot-type design with single-seat main valve
Hard-alloy treated valve core for durability
Flat and conical sealing methods
Complies with ANSI Class IV leakage standard
Large-area diaphragm with external detection mechanism
Excellent stability with primary pressure fluctuations
Handles varying secondary-side loads effectively

Performance Benefits:

Precise and reliable pressure reduction
Reduces high-pressure steam to safe working levels
Protects equipment from pressure-related damage

Installation Guidelines

This 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.
