A valve that lets you completely stop, but not modulate, the flow within a pipe
A valve with a gate-like disk that moves up and down at right angles to the flow when actuated by a stem screw and hand wheel. Gate valves are best for service that requires infrequent valve operation and where the disk is kept either fully open or closed.
1. A valve with a linear motion closure member that is a flat or wedge shaped gate which may be moved in or out of the flow stream. It has a straight through flow path. 2. A type of valve whose flow control element is a disc or plate that undergoes translational motion in a plane transverse to the flow passage through the valve body.
a valve that employs a sliding gate to open or close the passage in it.
Valve that uses a wedge or disc for opening and closing. The disc or gate clears the opening, which permits a straight line of flow, when the valve is opened. When the wheel is turned clockwise, the disc is moved into the closed position, which stops the flow. Gate valves are used when the valve remains either completely opened or closed for the greater part of the time, such as with a shut-off valve.
A valve having a slide or gate placed at right angles to the flow of the liquid and arranged to draw completely to one side when opened, thereby offering little obstruction to the flow, but completely stopping it when closed.
a (Control consisting of a mechanical device for controlling the flow of a fluid) valve that opens by lifting a round or
a mechanical device designed to open or close the flow pathway within a pipe or piping system
a type of slide valve that uses a flat or curved disc perpendicular to the process flow
a type of valve that includes a substantially rectangular-shaped gate that is moved by an operator in and out of the valve body to control the fluid
a valve with a two seated gate like disk moving perpendicularly to the fluid flow
Type of valve that uses a sliding "gate" across the face of the valve to control flow. Used with thick, heavy liquids.
a valve utilizing a rising and descending gate to control the flow of water.
A valve with a faucet handle used to restrict the flow of water in a line
A straight through pattern valve in which closure element is a wedge situated between two fixed seating surfaces, with means to move it in or out of the flow stream in a direction perpendicular to the pipeline axis. Used as a block valve, or on-off valve.
A type of valve in which the closing element (the gate) is a disc that moves across the stream in a groove or slot for support against pressure. A gate valve has relatively large full ports and a straight line flow pattern. Very little pressure drop however subject to leakage if sealing surfaces are scored or marred or if debris becomes lodged in grove. ( 081)
Valve with a gate that is opened or closed to control fuel flow; the locations for a gate valve are at one-mile intervals, at the bottom of hills (low points), and before and after critical gap crossings; this valve is used to stop flow at the tank or in the pipeline. A gate valve is either a rising-stem or nonrising-stem type. See also ball valve; check valve; nonrising-stem valve plug valve pressure-control valve; pressure- reducing valveq pressure regulating valve; rising-stem valve; thermal-relief valve.
Shut off valve that controls water service for lines 3” and larger.
Manual valve with straight-through flow using wedge type metal-to-metal or restricting partial seating surfaces. Not suitable for throttling section flow. Not suitable for section valves in an irrigation system.
A manually operated valve that isolates basement plumbing. Closing a gate valve will also prevent sewer backup from entering floor drains.
A valve regulated by the position of a circular plate.
A valve utilizing a wedge-shaped gate, which allows fluid flow when the gate is lifted from the seat.
A type of valve where flow is stopped by a sliding plate that is controlled by a turning handle. The handle typically turns a dozen or so times to close the valve. Back to glossary index.
It is a sliding gate which moves up or down to block the flow. Often used as isolation valves. Never used as control valves.
A valve capable of stopping or reducing the flow within a pipe.
A stop valve using the wedge-and-double-seat principle. It may be used to control fluids containing some solids, for when wide open, it operates on a straight-through flow. There is little likelihood of its becoming obstructed.
A type of control valve in which the mechanism acts as a gate. Control valve with a solid plate operated by a handle and screw mechanism. Rotating the handle moves the plate into or out of the waterway.
A valve with the closing element that is a disc which is moved across the stream, often in a groove or slot, for support against pressure.
A Gate Valve, or Sluice Valve, as it is sometimes known, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel.
