Membrane pressure relief valve for silo protection
Ensure immediate pressure stabilization in your bulk storage silos with a responsive solution designed to mitigate risks and enhance safety during fluctuating conditions.

Regulates and Balances Silo Pressure
The VHS-C Membrane Pressure Relief Valve from WAMGROUP is a crucial engineered-to-order solution designed to maintain optimal pressure levels within silos, preventing structural damage from unexpected pressure fluctuations. This valve enhances safety by instantaneously re-establishing pressure balance through its innovative membrane technology, making it ideal for industries ranging from construction to pharmaceuticals.
The lightweight, corrosion-free design features a SINT engineering polymer casing with a vertical carbon or stainless steel spigot for durability in harsh environments. Its real-time response to pressure changes ensures that air can seamlessly flow in or out, maintaining stability without the delays of spring-loaded mechanisms.
The VHS-C valve is adaptable for diverse applications, including concrete block manufacturing, detergent production, and fertilizer processing. Its seamless integration into existing systems is facilitated by its mechanical setup compatible with inductive signaling sensors, allowing for efficient automation and remote monitoring.
Designed for low maintenance, the self-cleaning elbow and limited component count minimize operational downtime and costs. Configurable options, such as EN 1935/2004-compliance and bird nets, provide further customization to meet specific industry standards and operational conditions. This valve not only ensures silo safety but also reduces environmental impact by minimizing emissions during use.
