Strainers

Y Strainer

Pipeline debris protection for pumps, meters, control valves and process equipment.

Y Strainer

Engineered around the medium, pressure, temperature and operating duty.

Product overview

Compact pipeline strainer that removes debris from the flowing medium to protect pumps, meters, control valves and downstream equipment.

Greysen reviews the complete operating case before confirming the valve. Body style, wetted materials, sealing system, connection standard and operator are matched as one project configuration.

CONFIGURATION OPTIONS

Materials and sealing selection

Material combinations are reviewed against corrosion, erosion, temperature and required service life. The final approved data sheet defines every pressure-containing and wetted component.

Body

Cast iron, ductile iron, carbon steel or stainless steel

Trim

Perforated stainless steel screen with optional mesh

Seat & seals

Cover gasket selected for medium and temperature

Connection

Threaded, socket-weld, butt-weld or flanged

VALVE + OPERATOR

Operation and automation

Manual and automated packages are selected using the valve operating load, maximum differential pressure, required speed and available site utilities.

Manual operation

Lever, handwheel or gearbox options are matched to size, torque and access.

Pneumatic actuation

Double-acting or spring-return packages can include solenoid, switch box and positioner.

Electric actuation

On/off or modulating actuators are configured for voltage, duty, enclosure and control signal.

Package verification

Torque or thrust, safety factor, mounting interface, travel time and fail position are checked together.

APPLICATION REVIEW

Information for correct selection

  1. Nominal size, pressure class and mating connection standard.
  2. Medium, concentration, solids and minimum/maximum temperature.
  3. Normal and maximum differential pressure, flow rate and cycle frequency.
  4. Manual or actuated operation, fail position, control signal and required travel time.
