C-G5 & C-G9 Wafer Gate Valves

C-G5

The C-G5 is a compact and rugged valve of a unique design. It is a wafer thin valve using an oval, bolted body with integral raised faces and is drilled and tapped to suit the pipeline flanges.

C-G9

The C-G9 valve has a flat, fabricated body with integral raised faces and is drilled and tapped to suit pipeline flanges. The valve is opened by withdrawing a circular gate into a fabricated bonnet.
The bonnet is formed by pressure during manufacture to produce a very strong but relatively light component.

Materials

Forged or wrought Carbon steels and low temperature carbon steels, with options for weld overlay and epoxy / phenolic lining, stainless steels, and Ferralium.

Gate, Seat Rings & Stems

Electroless Nickel Coated Carbon Steels with options for weld overlay, stainless steels, or hard facing (Tungsten Carbide or Stellite)

Seals

Specially compounded Nitrile synthetic rubber, Nylon PA12G, with options for Viton and HNBR

Applications

General low pressure, wafer gate valve service for use on tank farms, manifolds, terminals, jetties and platforms. Also suited to vacuum, high temperature and corrosive duty.

Standard Features

Bubble-tight sealing from vacuum to full rated pressure
Stem Protector
Life lubricated bearings – no routine maintenance
Upstream and downstream seal under all operating conditions – full block and bleed capability
Metal-to-metal primary seal – protected ‘O’ ring secondary seal installed in the gate and therefore out of the flow
Floating parallel sided gate can’t stick, wedge or gall
Floating spring loaded seats always in contact with the gate
Piggable

OPTIONS

Stem packing with sealant injection
Extended blow down valves
Stem extensions for operating underground
Transition Pieces
Gate supports for operation in a horizontal plane
