Materials of parts:
Body and Bonnet: ASTM A216 WCB, ASTM A352 LCB, ASTM A351 CF8M, ASTM A351 CF8, ASTM A351 CF3M, ASTM A351 CF3, ASTM A217 WC6, ASTM A217 WC9, ASTM A351 CD3MN.
Disc: ASTM A105+ENP, ASTM A350 LF2+ENP, ASTM A182 F304, ASTM A182 F316, ASTM A182 F304L, ASTM A182 F316L, ASTM A182 F51.
Seat: ASTM A105+ENP, ASTM A350 LF2+ENP, ASTM A182 F304, ASTM A182 F316, ASTM A182 F304L, ASTM A182 F316L, ASTM A182 F51.

UNIQUE Slab Gate Valve also named "Through Conduit Gate Valve" are manufactured and tested in accordance with the API 6D standard. Slab Gate Valves are manufactured with a full bore port, rising stem, OS & Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
