Product Details

Ceramic rotary valve supplyIntroduction:

The piston rod and sealing packing of the pneumatic actuator do not come into direct contact with the medium, greatly extending the service life of the pneumatic actuator. At the same time, the innovative design effectively solves the problem of material leakage at the shaft seal of similar valves. The valve body is made of precision cast steel, and the sealing packing is made of wear-resistant and high-temperature resistant fluororubber seals or flexible graphite. The sealing surface between the valve plate and the valve seat is made of wear-resistant and toughening structural ceramics, with a smooth surface and a hardness of up to 88HRC, which solves the problem of easy erosion and low service life of the sealing surface due to material erosion. The service life is 5-10 times longer than that of ordinary material valves, bringing ideal use and economic benefits to users, greatly improving the safety and stability of equipment operation. It is mainly suitable for the opening and closing of the dry ash system bin pump or economizer feed valve in power plants, as well as for the opening and closing of the feed of dust media with wear and corrosion in mines, petrochemical plants, cement plants, etc. This valve has good sealing performance, strong wear resistance, flexible opening and closing, and no sticking or accumulation of dust.

Ceramic rotary valve supply

Scope of application:

1. Dry ash system in thermal power plants (used as inlet and outlet valves, vent valves, balance valves, exhaust valves, drain valves, and ash discharge valves).

2. Bulk material conveying systems in industries such as cement, chemical, metallurgical, papermaking, and pharmaceuticals.

3. Various media with wear and tear are used for opening and closing on pipelines.

Performance characteristics:

1. Flexible opening and closing, reliable sealing

2 can replace double gate valves, bell jar valves, etc., without maintenance or repair

The nominal pressure of the pneumatic actuator is 0.4-0.6Mpa, and the nominal pressure of the valve is 1MPa

4 adopts pneumatic transmission method, non-standard can be customized

No external leakage
The standard rotary valve has a leakage rate 100 times better than the standard globe valve design. The movement of the globe valve stem pulls out dust and brings sand into the valve, damaging the graphite packing. In the rotary valve, the valve stem does not move in or out, but rotates to avoid damaging the packing and preventing external leakage.
Smooth operation
Rotary valves can uniformly and continuously transport materials, with a compact structure, smooth operation, and low noise. And due to the distance between the bearings and gearbox from the housing, it has improved high temperature resistance and lubrication.
