German AZ Pneumatica valves, AZ Pneumatica models, AZ Pneumatica prices

AZ Pneumatica valves are special valves where the closing member remains normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above a specified value, the valve discharges the medium to the outside of the system to prevent the pressure from exceeding the specified limit. Safety valves belong to the category of automatic valves and are mainly used on boilers, pressure vessels, and pipelines to control pressure within specified limits, playing an important role in protecting personal safety and equipment operation. Note: Safety valves must undergo pressure testing before use.

AZ Pneumatica valve functions and applications

Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve opens to discharge part of the gas/fluid from the system into the atmosphere or outside the pipeline, ensuring that the system pressure does not exceed the allowable limit, thereby preventing accidents caused by excessive pressure.

AZ Pneumatica valve assembly precautions

Cleaned components must be stored in a sealed manner for installation. The installation process requires the following: 1) The installation workshop must be kept clean, or a temporary clean area must be set up, for example, using newly purchased striped tarpaulins or plastic films, to prevent dust from entering during installation. 2) Assembly personnel must wear clean pure cotton work uniforms and pure cotton caps, with no hair exposed. They must wear clean shoes and degreased plastic gloves. 3) Tools used for assembly must be degreased and cleaned before assembly to ensure cleanliness.

AZ Pneumatica valve classification

Safety valves are mainly divided into two categories: spring-loaded and lever-loaded. Spring-loaded types rely on spring force for sealing between the valve disc and seat. Lever-loaded types rely on the force of a lever and weight. To meet high-capacity requirements, there is also a pulse-type safety valve, also known as a pilot-operated safety valve, which consists of a main safety valve and an auxiliary valve. When the medium pressure in the pipeline exceeds the specified value, the auxiliary valve opens first, allowing the medium to enter the main safety valve through the guide tube, opening the main valve and reducing the increased medium pressure. The discharge capacity of a safety valve is determined by the seat diameter and the opening height of the valve disc. It can be further divided into two types: micro-lift type, where the opening height is (1/20) to (1/40) of the seat inner diameter, and full-lift type, where it is (1/3) to (1/4). Additionally, depending on usage requirements, there are closed and open types. Closed types prevent the discharged medium from leaking out, directing it entirely through the specified outlet, generally used for toxic and corrosive media. Open types are generally used for non-toxic or non-corrosive media.
