Gate Valves
Full-bore isolation valve with rubber-encapsulated wedge for clean water distribution.
Engineered around the medium, pressure, temperature and operating duty.
Full-bore isolation valve with a rubber-encapsulated wedge, developed for low head loss and reliable shut-off in water distribution and utility pipelines.
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
Unobstructed bore minimizes pressure loss and sediment accumulation.
Encapsulated wedge compensates for minor wear and surface irregularities.
Non-rising stem design suits chambers and buried service.
Replaceable stem seals simplify planned maintenance.
CONFIGURATION OPTIONS
Material combinations are reviewed against corrosion, erosion, temperature and required service life. The final approved data sheet defines every pressure-containing and wetted component.
Ductile iron with fusion-bonded epoxy coating
EPDM- or NBR-encapsulated wedge; stainless steel stem
Resilient wedge-to-body sealing
Flanged, grooved or mechanical-joint options
VALVE + OPERATOR
Manual and automated packages are selected using the valve operating load, maximum differential pressure, required speed and available site utilities.
Lever, handwheel or gearbox options are matched to size, torque and access.
Double-acting or spring-return packages can include solenoid, switch box and positioner.
On/off or modulating actuators are configured for voltage, duty, enclosure and control signal.
Torque or thrust, safety factor, mounting interface, travel time and fail position are checked together.
