PVC / UPVC Ball Valve

Corrosion-resistant isolation valve for chemical handling and water treatment.

PVC / UPVC Ball Valve

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

Product overview

Lightweight corrosion-resistant ball valve for water treatment, chemical dosing and utility systems where metallic corrosion is a concern.

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.

DESIGN DETAILS

Features and benefits

01

Valve construction

True-union design allows removal without cutting the pipe.

02

Sealing performance

Thermoplastic construction resists many corrosive media.

03

Reliable operation

PTFE seats provide low torque and tight shut-off.

04

Project flexibility

Manual and compact actuated configurations are available.

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

UPVC, CPVC, PP or PVDF according to service

Trim

Matching thermoplastic ball and stem

Seat & seals

PTFE with EPDM, FKM or compatible seals

Connection

True-union socket, threaded 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.
