JCH-TIKTOP  Specializing in R&D, Production and Sales of Mining Fluid Control Valves.

We focus on the R&D, production and sales of mining fluid control valves. Aiming at automated pipeline working conditions such as mineral processing, tailings transportation and solid-liquid separation, we professionally develop a series of Electric Pinch Valves (Electric Hose Valves).Driven by electric actuators, these valves open, close and regulate flow by squeezing wear-resistant rubber sleeves. They feature non-clogging, wear resistance, reliable sealing and remote automatic control, effectively solving problems such as jamming, wear and leakage of traditional valves in particle-laden slurry pipelines.They are widely used in high-automation scenarios including mineral processing plants, tailings dry stacking, filter press pipelines and wastewater treatment.

I. Product Introduction of Electric Pinch Valves

Electric pinch valves mainly consist of valve body, wear-resistant rubber sleeve, electric actuator and connecting bracket.The thrust of the electric actuator squeezes the sleeve to deform, realizing pipeline on-off and flow regulation.The internal flow passage of the sleeve is smooth and straight, without valve core or gate plate, so there is no material hanging or jamming.It is especially suitable for complex working conditions such as ore pulp, tailings slurry, mud and corrosive media, serving as a core control valve for automated mining transportation pipelines.

II. Main Product Types

By Connection Type

• Flanged Electric Pinch Valve: Firm connection, stable pressure bearing, suitable for main mining pipelines and large-diameter transportation pipelines

IX. FAQ

Can electric pinch valves be used in automated ore pulp pipelines?

Yes. They can be directly connected to PLC / DCS systems for remote on-off and flow regulation, suitable for automated mining production lines.

What is the difference between electric and pneumatic pinch valves?

Electric pinch valves are driven by electricity without needing an air supply, more suitable for sites without air source and scenarios requiring precise flow regulation.

What is the core wearing part of a pinch valve?

The core wearing part is the rubber sleeve, which is quick and easy to replace without professional tools, resulting in extremely low maintenance cost.

What parameters are required for custom electric pinch valves?

Accurate selection can be completed by providing pipeline nominal diameter, working pressure, medium characteristics, control type (on-off / modulating) and installation method.
