J-VALVES
1" 150LB WPB Basket Strainer
Structural Features
WPB Carbon Steel Material: The valve body is forged or cast from ASTM A234 WPB carbon steel. It features high strength, excellent weldability and moderate corrosion resistance, delivering cost-effective performance.
Basket Strainer Structure: Built-in cylindrical basket screen offers large filtration area, low pressure drop and high dirt holding capacity to effectively trap solid contaminants.
Flanged Connection: Adopts RF (Raised Face) flange complying with ASME B16.5 standard. 1" nominal size and Class 150 pressure rating ensure great interchangeability for installation.
Top Opening Design: The strainer cover is bolted. It can be quickly opened from the top, so the screen can be removed for cleaning or replacement without dismantling pipelines.
Drain Port: An optional drain port is available at the bottom for on-line draining and system emptying, minimizing downtime.
Pressure Balance Design: Selected models are equipped with pressure balance holes or bypass valve ports to facilitate pressure relief during screen replacement.
Compact Structure: Small size and light weight require limited installation space, easy to integrate into existing pipeline systems.

Application Fields
Oil & Gas Industry: Applied in oil & gas gathering pipelines, metering stations and pressure regulating stations. It filters out sand, rust and other impurities to protect downstream equipment.
Chemical Industry: Used in chemical raw material pipelines and reactor feeding systems. It intercepts solid particles to maintain stable production processes.
Power Industry: Suitable for boiler feed water systems and cooling water circulation pipelines, preventing impurities from entering pumps and heat exchangers.
Pharmaceutical Industry: Installed in raw material delivery pipelines to guarantee medium cleanliness and meet production hygiene standards.
Food & Beverage Industry: For process water and raw material conveying pipelines (stainless steel version required) to ensure product safety.
HVAC Industry: Used in cooling water and hot water circulation systems to protect water pumps and heat exchangers and extend service life.
General Industry: Widely applied in compressed air pipelines, steam pipelines and industrial water systems for general impurity filtration.
Advantages & Benefits
High Filtration Efficiency: The basket structure provides large filtration area with lower pressure drop under the same flow rate, reducing energy consumption.
Easy Maintenance: Top opening design allows quick screen removal and cleaning without pipeline disassembly, greatly cutting downtime.
Cost-Effective: WPB carbon steel features high cost performance, ideal for working conditions without strong corrosion and lowering procurement costs.
Standardized Installation: 1" Class 150 RF flange is a standard specification, fully compatible with existing pipeline systems for easy installation.
Equipment Protection: Effectively traps solid contaminants and extends the service life of downstream pumps, valves, instruments and heat exchangers.
Reliable Operation: Simple structure with no moving parts ensures low failure rate and high long-term operational stability.
Customization Service: Screen mesh, material and structural dimensions can be customized to meet special working condition requirements.
Selection Guide
Media Corrosiveness: For corrosive media, select strainers made of 304 or 316 stainless steel.
Operating Temperature: For working temperature above 300℃, use spiral wound gaskets or metal sealing structure.
Filtration Rating: Select proper mesh according to downstream equipment protection demands; 40-60 mesh is recommended for general pump protection.
Pressure Drop Requirement: For high flow rate or low allowable pressure drop conditions, adopt larger size or parallel installation.
Drainage Requirement: Equip with bottom drain valve port if on-line drainage is needed.
