German Hawe valves Hawe models Hawe prices

Hawe 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 prevents the pressure from exceeding the 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 within specified limits, playing an important protective role for personal safety and equipment operation. Note: Safety valves must undergo pressure testing before use.

Hawe valve functions and applications

Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve opens and discharges 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.

Hawe 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 cloth or plastic film, 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.

Hawe valve classification

Safety valves are mainly divided into two categories: spring-loaded and lever-operated. In spring-loaded types, the seal between the valve disc and valve seat is maintained by the force of the spring. Lever-operated 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 and open it, thereby reducing the increased medium pressure. The discharge capacity of a safety valve is determined by the valve seat diameter and the opening height of the valve disc, and can be divided into two types: micro-lift type, where the opening height is (1/20) to (1/40) of the valve 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, and are generally used for toxic and corrosive media. Open types are generally used for non-toxic or non-corrosive media.
