THROUGH CONDUIT EXPANDING GATE VALVE

Maverick’s Through Conduit Expanding Gate Valve
enables double block and bleed functionality to be
achieved within one single valve assembly as opposed
to the two conventional slab gates that would otherwise
be required.

The benefits include an overall cost, size and
weight reduction in addition to an ability to configure the
valve to seal in either the closed position (single expanding)
or open and closed position (double expanding).

BENEFITS

• Corrosion resistant
• Fast closure
• Gas tight sealing
• Inherently fail safe

APPLICATIONS

Emergency shut down, flow-line, HIPPS, HP/HT, hot tapping,
isolation, manifold, pig launching and receiving, PLEM,
PLET, riser module, xmas tree
