Válvulas de compuerta de cuña de cerámica

Especificación:

Aplicaciones Típicas:

For some very hard particles or serious erosive mediums, general metal seated wedge gate valves will be washed out and damaged easily due to the abrasion and or corrosion. As a professional and experienced ceramic valve manufacturer, FUVALVE desarrolla ceramic wedge gate valves to solve the corrosion and abrasion problems for wedge gate valves.
FUVALVE’s ceramic wedge gate valves are very suitable for those mediums contain fibers and hard solid particles, such as below listed typical applications:
Mining slag
Lavado de carbón
Ash Slurry
Suspension
Oil with particles
Catalyst

Caracteristicas de diseño:

Tipo de producto

1. The valves have two main structures: bolted (BB) bonnet type for low pressure ratings and pressure seal bonnet (PSB) for higher pressure.

2. Inlet seat and outlet seat are ceramics materials. By using the high hardness and high strength of high pure 99% Cerámica Al2O3, FUVALVE ceramic wedge gate valves have much longer service life than general metal seated wedge gate valves in similar conditions.

3. Two ceramic sealing rings are inserted to both sides of wedge gate. Besides the inlet and outlet seats are also ceramics, this ceramics-to-ceramics design can avoid abrasion and corrosion, which makes ceramic wedge gate valves have much longer service life than general metal seated wedge gate valves.

4. The actuation of FUVALVE ceramic wedge gate valves can be hand wheel, electric motor and hydraulic actuator, special requirements are available on customer’s require.
