bevel gear stainless steel 304 penetrating knife gate valve

product structure

CTDZ573X is a manual gear driven through type knife gate valve. The operator drives the gate to rise and fall linearly through the handwheel and gear transmission mechanism to achieve pipeline opening and closing. The product configuration involves two pressure levels, PN6 and PN10, as well as two valve body materials, WCB and 304; When selecting, it is necessary to separately check the required diameter, sealing structure, and actual driving device. Different specifications and material configurations cannot be directly considered interchangeable.

Why use gear transmission?

When the diameter is larger or the operating torque is higher, the manual operating force can be reduced by a gear reduction mechanism. The specific reduction ratio, handwheel direction, and operating torque should be determined by the actual valve and driving device.

What medium is suitable for penetrating structures?

The selection can be based on the working conditions of slurry, sewage, fiber, and particulate media, but it is necessary to confirm the particle size, concentration, abrasiveness, and whether it is easy to deposit at the same time. It cannot be generalized that all particulate media will not block.

Sealing and Materials

The gate and valve seat of CTDZ573X need to be combined with the particle size, concentration, abrasion resistance, and working pressure difference of the slurry or particle containing medium to select the sealing structure. The valve seat material, sealing contact form, and opening and closing frequency will affect the actual closing performance and maintenance cycle; The sealing ability should be evaluated based on the corresponding product structure and testing requirements, and cannot be judged solely by the penetrating structure.

Frequently Asked Questions

Is the bevel gear knife gate valve an automatic valve?

This valve uses a manually operated gear transmission. Electric or pneumatic operation requires the corresponding actuator and mounting arrangement.

Is stainless steel 304 necessarily suitable for corrosive media?

Not necessarily, material selection should be based on the composition, concentration, temperature, and corrosiveness of the medium.

How to choose the valve seat for a penetrating knife gate valve?

It is necessary to determine the soft seal or other structural scheme based on particle abrasion, medium temperature, pressure, and allowable leakage level.
