Product Description
Pneumatic Pinch Valve with Intelligent Electro-Pneumatic Positioner for Mining Slurry Flow Control
The VESON Pneumatic Pinch Valve with Electro-Pneumatic Positioner delivers precise modulating flow control for the most demanding mining slurry applications. The combination of a fast-acting pneumatic actuator with an intelligent smart positioner enables accurate throttling of abrasive slurries that would destroy conventional control valves within weeks.
Key Features
- Smart Positioner Technology: 4-20mA input with optional HART protocol for remote configuration, diagnostics, and predictive maintenance alerts
- Fast Actuation: Pneumatic diaphragm actuator delivers full stroke in under 3 seconds for rapid process response
- Modulating Control: Precise flow regulation from 0-100% stroke with linear or equal percentage characterization
- Replaceable Sleeve: Quick-change reinforced rubber sleeve design minimizes downtime to under 15 minutes per replacement
- Self-Cleaning Action: Pinch mechanism flexes the sleeve on every stroke, preventing solids buildup and scale formation
- Fail-Safe Options: Spring-return actuator available for fail-open or fail-close on loss of air supply
