Spring-loaded Pressure Relief Valves VCP Brochure

Product catalog summary

Overview: The VCP Pressure Relief Valves are designed to protect silo structures from abnormal pressure conditions. They consist of a cylindrical casing with a weld-on spigot, a disc-shaped inner lid for negative pressure, an outer steel ring for excess pressure, gaskets, and a weather protection cover.

Functionality: Helical springs keep the valve lids closed under normal pressure conditions. The outer lid is held by three spring rods and opens when internal pressure exceeds preset limits, allowing pressure to escape. The inner lid, held by a single spring rod, opens under suction pressure to allow air entry, balancing the pressure.

Technical Specifications: The valves are available in carbon steel or stainless steel, with body diameters of 273 mm or 356 mm. They support air volumes up to 7,000 m3/h for VCP273 and 13,000 m3/h for VCP375. Standard versions are preset for a maximum negative pressure of -0.005 bar and a maximum excess pressure of +0.05 bar. Calibration can be adjusted with special spring kits.

Benefits: The valves are lightweight, easy to handle, highly resistant to atmospheric agents, easy to install, and require quick maintenance.

Options & Accessories: Available options include an ATEX-certified version for zone 21, inductive proximity sensors, and an inspection hatch.

Performance & Features: The valves are equipped for inductive signaling sensors and are calibrated by the manufacturer for specific pressure settings. They are designed for high resistance and easy maintenance.

Spring-loaded Pressure Relief Valves VCP Brochure-2

VCP Pressure Relief Valves consist of a cylindrical casing with clamped weld-on spigot, a disc shape inner steel lid for negative pressure operation held in position by a central spring rod, an outside steel ring for excess pressure kept in position by three spring rods, gaskets, and a weather protection cover. Function In the VCP Pressure Relief Valve, helical springs keep the valve lids closed when the pressure value remains within the preset limits. The three outside spring rods keep the external ring-shaped lid firmly closed as long as the force generated by the pressure inside the silo does...
