The power station swing check valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The
medium does not change its flow direction when it flows through the stop valve. The pressure is self-tightly sealed, and both ends of the valve are
welded connections. The valve petals are closed quickly, the water hammers are low pressure, the body structure is simple, the production is better, the sealing performance is good, and the dense cover is less erosion. The scope of applications is wide.
Application Scenarios: The power station swing check valve is generally used in places with harsh service conditions, such as high temperature and high pressure thermal power plants, power industry, petroleum refining and other fields.

RAYS Three-Way and Multi-Port Ball Valve are important components in fluid control systems and are widely used in various industrial fields. They are variants of ball valves. Their design allows fluids to be distributed or converted between more than two pipes. The three-way ball valve has three interfaces, which can realize the diversion, confluence or switching of fluids. According to the different internal structures, it is divided into L-type and T-type. The L-type can only connect two mutually orthogonal pipes, and cannot simultaneously maintain the interconnection of the third pipe, and only plays a distribution role; the T-type can make three orthogonal pipes interconnected and cut off the third channel, playing a diversion and confluence role. The multi-way ball valve is an extension of the three-way ball valve, with more interfaces and more complex fluid control functions.
Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
