VST 08-1 plastic air supply valve with deflector

Plastic plate valves for air supply have an easily adjustable center element for flow control. The valve is equipped with a pressure measuring hole. As standard, the plate valve is fitted with an adjustable deflector to restrict the supply air flow into the space at 180˚. The plate valve is provided with a sealing tape for sealing in the mounting ring. Plastic valves can be cleaned with mild solutions of non-aggressive detergents. VST valves are made of polypropylene, colour white (RAL9003). They can withstand some diluted chemicals. The highly advantageous aerodynamic shape reduces valve noise and significantly reduces the risk of crosstalk.

Installation

The valves are inserted by flat springs into the VLZ wall, which allows the valve to be fixed into a ceiling structure, wall or pipe. A plate valve is inserted from one side of the brickwork, a flexible flex head is inserted from the other side and the joint is fixed with steel or nylon clamping tape. The wall can also be fixed in a circular pipe. For pipes Ø 150 and Ø 160, use the appropriate VLZ brickwork and always use a plate valve Ø 160.

Measuring and control

The air flow control is carried out by rotating the centre disc, which changes the valve opening "a" (mm). Air flow measurement is performed as a pressure differential measurement using a measuring tube. See diagrams for more details.
