Reliable quarter-turn isolation for plumbing, HVAC and light industrial service.
Engineered around the medium, pressure, temperature and operating duty.
Product overview
Corrosion-resistant quarter-turn ball valve for plumbing, HVAC and light industrial isolation, providing compact installation and fast positive operation.
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.
Typical technical specification
Nominal sizeDN8–DN100 (¼–4 in)
Pressure ratingCommonly PN16–PN40, depending on size and temperature
Body materialsBrass, bronze or specified copper alloy
Disc / trimChrome-plated brass or stainless steel ball
Seat / sealingPTFE or reinforced PTFE
End connectionThreaded, solder, compression or flanged options
PTFE seating provides low torque and dependable shut-off.

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.
