Membrane pressure relief valve for silos and bins
Ensure silo safety with our valve that instantly balances internal pressure, preventing structural damage and ensuring efficient operation during both excess and suction pressure scenarios.
The VHS Membrane Pressure Relief Valve from WAMGROUP is designed to swiftly manage pressure imbalances in industrial silos, preventing structural compromise while maximizing dust recovery. Featuring a dual-function membrane for instantaneous pressure regulation, it excels in safeguarding silos across diverse sectors like construction, food processing, and chemicals. The valve’s stainless steel construction ensures high corrosion resistance, complementing its integration with centralized suction systems. Preset to handle pressures from -0.005 to 0.05 bar, the VHS valve is engineered for continuous operations, offering reliable performance with minimal maintenance. Fully compliant with European safety standards, it supports customization options and inductive sensors for enhanced operational flexibility.
