Externally mounted line valves effectively stop the flow of material to vacuum receivers for trouble-free operation of common or single material line conveying systems.
At rest, the inlet is closed, allowing the valve to isolate the receiver from the common material line of central systems. When the vacuum sequence valve opens, the line valve allows material to fill the receiver.

High Performance: The high performance line valve has a stainless steel inlet and outlet, includes a high temperature Viton seal in the pneumatic cylinder and a specially plated and heat-treated valve body, lid and plunger for maximum wear-resistance. The high performance valve is optimized for use with high temperature materials, those exceeding 225°F {107°C}, and for highly abrasive materials including glass-filled resins and sharp regrind.
Vacuum Valve Operation: Although specifically designed to handle the flow of material, common line valves may also be used for controlling air flow, to shut off the flow of vacuum air to receivers, or operate in response to vacuum control systems for pumps.
