STRATE BEV-GF Two-stage valves

The BEV-F is a single-stage valve offering only the function of the second ventilation stage (fine ventilation) provided by the two-stage valve (BEV-GF). For ventilation quantities of 20 to 40 m3/h. Specific applications include high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required, as well as at high points with low flow quantities. Type F (fine ventilation): Air escapes through this valve, and collected gases cause it to open once again, including under operating pressure, until the medium continues to flow and close the valve again. Installed at high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required. Installed at high points of pressure lines with low flow quantities.

The special lightweight aluminium design and silicone inserts of STRATE sandwich non-return valves SB makes them ideal for: Conveying air and gases up to temperatures of 200 °C Working pressures up to 4 bar Special applications with other valve insert materials on request

STRATE valve shafts are used in industrial and municipal areas. The different design sizes of the STRATE AWALIFT valve shafts allow the optimum size to be assigned to every individual purpose. Pipe and cable ducts, which are located exactly according to customer specifications in the manufacturing plant, meet all requirements for an exact fit, safety and ease of maintenance. Optimum, safe installation locations for valves and system components whose size allows them to be housed in a shaft Are excellently suitable as inspection shafts with flushing connection, as feeding points for AWAaerob ventilation systems, for ventilation and bleeding valves, for pig traps etc. Are made of high-quality, durable and waterproof materials with a high material strength and low material weight, with the design permitting short installation times and excluding complex

AVUSE-1 for degassing under pressure, AVUSE-3 for degassing, high flow rate air inlet and outlet. Simple but studied design – To reach the best performances with optimized components. Ventilation area protected – From splashes and clogging thanks to a specific deflector design, ensuring a long term operation. Polymeric high-quality material. Easy maintenance – Thanks to quick removal of the clamps and drainage cock.
