Pressure Relief & Control Valves VHS Brochure

Product catalog summary

Overview: The document provides technical specifications and applications for VHS Pressure Relief & Control Valves, designed to manage pressure within silos, bins, hoppers, or containers. These valves prevent both excess and negative pressure, safeguarding personnel and equipment.

Specifications: The VHS273 model operates within a pressure range of -50 mm H2O to 1000 mm H2O. It is available in carbon steel or stainless steel (304) for parts in contact with the product. The weather protection cover is made of stainless steel, and gaskets are tailored to the application.

Applications: These valves are mounted on top of storage units to prevent dangerous pressure conditions that could harm people or damage structures. They are essential for maintaining operational safety by automatically adjusting to pressure changes during filling and emptying processes.

Technical Advantages: The valves offer rapid restoration of normal conditions, handle flow rates up to 5000 m3/h, and minimize the risk of crust or block formation inside the valve. They are designed for easy maintenance and are ideal for enclosed environments with limited dust emissions, contributing to reduced environmental pollution.

Operational Details: The valves function by opening to release pressure or vacuum when air input and output are not balanced, thus preventing potential damage to the silo. Dust emissions can be managed through a duct connected to the outlet pipe.

Certifications: The product is manufactured by WAM S.p.A., a company certified under UNI EN ISO 9001-2000 standards.

Pressure Relief & Control Valves VHS Brochure-3

Pressure Relief Valve For a correct operation the application of a pressure relief valve is necessary in order to discharge possible pressure inside the silo, as well as negative pressure. In fact, there is pressure once you fill the silo and negative pressure when you empty it. lf air input and output are not correct the valve opens (one way or the other) and avoids possible silo damage. The dust emission can be channeled through a duct which is connected with the outlet pipe.
