Pneumatic valve works

Pneumatic valve is the use of compressed air-driven valve. Pneumatic valve procurement only a clear specification, type, pressure to meet the procurement requirements of the practice in the current market economy environment is imperfect. Because the pneumatic valve manufacturers in order to compete for products, each in the design of pneumatic valve under the concept of a unified, innovative, formed their own corporate standards and product personality. Therefore, pneumatic valve procurement more detailed technical requirements, and manufacturers to obtain consensus, as a pneumatic valve procurement contract annex is necessary. This type of valve in the pipeline should be generally horizontal installation. Pneumatic valve working principle The use of compressed air to promote multi-group combination of pneumatic actuators in the actuator movement, transmission of force to the characteristics of the beam and the inner curve of the track, driven by the hollow core spindle for rotational movement, compressed air to the cylinder, change the inlet and outlet gas Position to change the direction of spindle rotation, according to the load (valve) torque required for the rotation, the number of cylinder combinations can be adjusted to drive the load (valve) work.

Overhead Sectional Door

Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.

The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.

The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147

For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.

A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.

The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.

Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
