Flat 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.
RAYS C-type ball valve adopts a double eccentric design: the rotational center (axis) of the C-ball is offset from both the geometric center (sphere) of the C-ball sealing surface and the sealing center of the seat. This double eccentric design results in a dual-vector cam motion involving both rotation and translation of the C-ball, facilitated by the stem being offset in two planes. When the valve is closed, the C-ball and the seat interact to create a cam-action wedge tightness, achieving a torque seal. The torque required for sealing is provided by a handle, gear, or actuator, ensuring a tight shut-off that is mechanically independent of springs or process pressure
RAYS cast steel check valves are designed and manufactured to provide maximum service life and dependability. All check valves meet the design requirements of American Petroleum Institute standard API600 & 6D.BS EN 13709 and generally conform to American Society of Mechanical Engineers standard ASME B16.34. Valves are available in a complete range of body/cover materials and trims.
