German Mac valve Mac model Mac price

Mac valve is a special valve whose closing member remains normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above the specified value, it prevents the medium pressure in the pipeline or equipment from exceeding the specified limit by discharging the medium to the outside of the system. Safety valves belong to the category of automatic valves and are mainly used on boilers, pressure vessels, and pipelines to control pressure so that it does not exceed the specified value, playing an important protective role for personal safety and equipment operation. Note: Safety valves must undergo pressure testing before use.

Mac valve function and application

The safety valve provides safety protection in the system. When the system pressure exceeds the specified value, the safety valve opens and discharges part of the gas/fluid in the system into the atmosphere or outside the pipeline, ensuring that the system pressure does not exceed the allowable value, thereby preventing accidents caused by excessive pressure.

Mac valve assembly precautions

Cleaned components must be stored in a sealed condition for installation. The requirements for the installation process are as follows: 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 workers must wear clean pure cotton work clothes, pure cotton caps with no hair exposed, clean shoes, and degreased plastic gloves. 3) Tools used for assembly must be degreased and cleaned before assembly to ensure cleanliness.

Mac valve classification

Safety valves are mainly divided into two categories: spring-loaded and lever-operated. In spring-loaded types, the sealing between the valve disc and valve seat relies on the force of the spring. Lever-operated types rely on the force of the lever and weight. To meet the need for large capacity, 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 pressure value, the auxiliary valve opens first, allowing the medium to enter the main safety valve through the guide tube and open the main safety valve, thereby reducing the increased medium pressure. The discharge capacity of a safety valve is determined by the diameter of the valve seat and the opening height of the valve disc, and can also be divided into two types: for micro-lift type, the opening height is (1/20) to (1/40) of the inner diameter of the valve seat; for full-lift type, it is (1/3) to (1/4). In addition, depending on usage requirements, there are closed and open types. In closed types, the discharged medium does not leak out but is entirely discharged through the specified outlet, generally used for toxic and corrosive media. Open types are generally used for non-toxic or non-corrosive media.
