Wedge Gate/ through conduit / Double expanding GATE VALVE Solid / Flexible/ Split /Parallel slide


The gate valve is the most widespread type of industrial pipeline valve. Its application area is very wide. There are different types of designs available depending on the construction of the closure elements. Recommended for on-off service, without throttling, for infrequent use, with minimal resistance to the flow.
For flow control, consult for a specially adapted design for this purpose.
Available designs: Solid Wedge, Flexible Wedge, Divided Wedge and Double Wedge.
Available materials: Cast steel, Forged steel, Stainless steel, Nickel alloys and Others.
Sizes from DN 50 (2”) up to DN 1200 (48”).
Pressure classes from PN16 (Class 150#) up to PN250 (Class 1500#).
Maximum temperature up to 595°C.
Connection types: Flanged, Welded, Others .

Standard Construction Features:

Body: Flow areas are specifically designed for minimum turbulence and pressure drop.

Bonnet Ample stuffing box area, Stellite® stem guide surface and back seat shoulder for accurate guiding of the stem and back seat.

Ball Bearing-type Yoke Sleeve Large, high-pressure valves can require a tremendous amount of torque to open and close. By utilizing ball bearings in the yoke sleeve the operating torques of these difficult-to-operate valves are reduced by as much as 50 percent.

Flexible Wedge Sealing Design: The flexible wedge is a one-piece, fully guided cast wedge with a central hub to allow the seating faces to move relative to each other, thus compensating for distortion of the body seats due to thermal expansion or piping loads. Seat ring and wedge seating face are set at a 9˚ angle from vertical to minimize sliding con- tact of the wedge and seat ring during opening and closing. Wedging actions help effect a tight seal in low differential pres- sure services. Flexible wedge construction resists wedge sticking or binding in services where the valve may be closed when cold and opened when hot. Seating surfaces are hardfaced with Stellite®6 to provide high cycle capability in very high differential pressure services.


Parallel Slide Design: The gate is a split design using two discs spring loaded and held together by a gate holder with an Inconel 750 spring to provide initial energizing when closed. The gate relies for seat tightness on the primary fluid pressure acting on the down- stream half. There is no wedging action or extra loading on the seats resulting in considerably lower operating torque. When the valve is in the open position the gate is completely clear of the seats. During closing there is a bevel on the bot- tom of the gate to guide it in between the seats and recompress the spring. Seating surfaces are hardfaced with Stellite®6 to provide high cycle capability in very high differential pressure services.

Gate Valves

Wedge Gate Valves

Solid Wedge Design:

The wedge is made in one solid piece being the downstream side the one which seals the valve when upstream pressure push the wedge againts te downstream seat.


Flexible Wedge Design

The wedge has a machined groove in its central part providing flexibility at the disc.


Split Wedge Design

The wedge is made in two separate parts providing high ability to seal. This is recommended when high thermal or mechanical deformations are expected due to working conditions.
