Stainless steel 304 electric clamp penetrating knife gate valve
Product Structure and Selection Instructions
The stainless steel 304 electric clamp penetrating knife gate valve adopts an electric actuator to drive the gate plate to move linearly, and cooperates with the clamp connection and penetrating knife gate structure to open and close the pipeline. The current product parameter table includes material options for PN10, stainless steel 304, and 316L. The specific diameter, material combination, and actuator configuration are subject to the actual technical conditions of the order.
What are the characteristics of the penetrating knife switch structure?
The penetrating structure is mainly used to reduce the risk of accumulation and blockage of slurry, particles or fiber media in the valve chamber. The actual effect is related to the particle size, concentration, valve seat structure, installation direction, and operating mode of the medium, and cannot be simply written as not blocking under all operating conditions.
Switch type and regulating type actuators
The switch type actuator mainly completes full opening and full closing; If the project requires adjustable control, the actuator, control signal, valve position feedback, and valve body should be separately confirmed for suitability for continuous throttling. 4–20mA or other control methods are not included as default configurations for this product.
Materials and Sealing
304 or 316L materials should be selected based on the corrosiveness of the medium, temperature, and operating conditions. The valve seat and sealing form need to be confirmed according to the medium particles, abrasiveness, allowable leakage level, and operating frequency, and should not declare "zero leakage" or fixed sealing structure without order basis.

Frequently Asked Questions
Does this electric knife gate valve support 4–20mA by default?
Not supported by default. Whether to configure 4–20mA needs to be confirmed based on the adjustable actuator and control module.
How to choose between 304 and 316L?
It should be determined based on the composition of the medium, corrosiveness, temperature, and project material requirements, and cannot be judged solely by the name "stainless steel".
Can penetrating knife gate valves be throttled for a long time?
Whether it is suitable for continuous throttling depends on the valve seat, gate, medium abrasion resistance, and actuator configuration; Products mainly used for opening and closing should not be directly used as regulating valves.
