The Power Plant Gate Valve has small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change its flow direction when the gate flows through the gate valve. The pressure is self-tightly sealed, and both ends of the valve are welded connections. The torque required for opening and closing is small, the body structure is simple, the manufacturing process is better, the sealing performance is good, and the corrosion of the dense cover when the full opening is less. The scope of applications is wide.
Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides and easy to install.

RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
RAYS Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
CW700 Series Bellows Seal Control Valves are divided into three major series: CSW701/CW701/CW702/CLW702 type bellows-sealed single-seat regulating valves and bellows-sealed cage-type regulating valves, as well as low-leakage bellows-sealed cage-type regulating valves. The bellows-sealed single-seat regulating valve is a regulating valve with top guide structure. The bellows-sealed cage-type regulating valve is a regulating valve with pressure balance. The valve body has an S-flow channel type passage, with small pressure drop loss, large flow rate, wide adjustable range and high flow characteristic accuracy. The low-leakage bellows-sealed cage-type regulating valve not only has the advantages of cage-type regulating valves, but also has a sealing ring between the valve core and the valve cage, reducing the leakage. The full series of upper valve covers adopt bellows-sealed structure, which can completely eliminate the possibility of medium leakage from the valve stem movement gap to the outside. When equipped with the RSMF series actuators, it has a compact structure, large output force and long service life. Therefore, it is widely used in automatic control systems of highly toxic, strongly corrosive, radioactive and rare and precious media. *CSW701Bellows Seal small-Port single-seat control valve *CW701 Bellows Seal single-seat control valve *CW702 Bellows Seal caged globe control valve *CLW702 Bellows Seal Low-leakage bellows caged globe control valve
