What are high-pressure valves?
High-pressure valves are specialized devices designed to withstand extreme pressure conditions in industrial processes. They are indispensable in applications where liquids, suspensions or gases need to be transported under high pressure. These valves not only ensure safe transport, but also minimize the risk of leaks or failures that could cause significant safety and environmental problems.
The challenge of high pressures
Dealing with high pressures poses numerous challenges. On the one hand, there is the risk of material failure, which can be caused by improper design or material fatigue. The tightness of the systems must also be guaranteed in order to prevent leaks. In addition, the maintenance of such high-pressure systems requires special expertise in order to minimize downtimes and reduce operating costs.
High pressure gate valve AT300
The GEFA AT300 is a DOMINO high-pressure gate valve that is used in pipe systems that can withstand operating pressures of up to 40 bar up to a nominal diameter of DN300. It is particularly suitable for conveying dewatered sewage sludge or biomass. The robust design with a two-part housing and a self-adjusting COMPACT cross seal ensures maintenance-free operation and reliability.
High pressure gate valve AT750
The GEFA AT750 is the ideal solution for even higher pressure requirements. This knife gate valve is designed for operating pressures of up to 100 bar and has a rising gate valve plate that is mounted on a pressure-shock-proof bearing. With its double-sided seal and the option of an adjustable secondary seal, the AT750 offers maximum safety and performance.
Applications of GEFA high-pressure gate valves
The main applications for GEFA high-pressure knife gate valves are in the conveying of mechanically dewatered sewage sludge or biomass with a high dry matter content. These systems are used on chamber filter presses, centrifuges for sewage sludge drying and in the piping systems of fermentation and biogas plants. Here, the valves have proven to be reliable and efficient for years.
