  | ValvePattern: The configuration of the ports of a valve according to either the linear route taken by a fluid flowing through the valve or by the number of ports where: SINGLEPORT: Valve that has a single entry port from the system that it serves, the exit port being to the surrounding environment. ANGLED_2_PORT: Valve in which the direction of flow is changed through 90 degrees. STRAIGHT_2_PORT: Valve in which the flow is straight through. STRAIGHT_3_PORT: Valve with three separate ports. CROSSOVER_4_PORT: Valve with 4 separate ports.
  | 弁の形: 単一ポートSINGLEPORT()=システムで単一入口ポートを持ち、出口ポートは周囲環境である　2ポート直角型(ANGLED_2_PORT)＝中で流れ方向が完全に90度変わる弁　2ポート直行型(STRAIGHT_2_PORT)＝中で流れが真っ直ぐな弁　3ポート直行型(STRAIGHT_3_PORT)＝3つの別々のポートを持つ　4ポート交差型(CROSSOVER_4_PORT)＝4つの別々のポートを持つ

- ValveOperation
  P_ENUMERATEDVALUE / IfcLabel / PEnum_ValveOperation: DROPWEIGHT, FLOAT, HYDRAULIC, LEVER, LOCKSHIELD, MOTORIZED, PNEUMATIC, SOLENOID, SPRING, THERMOSTATIC, WHEEL, OTHER, NOTKNOWN, UNSET

  | ValveOperation: The method of valve operation where: DROPWEIGHT: A valve that is closed by the action of a weighted lever being released, the weight normally being prevented from dropping by being held by a wire, the closure normally being made by the action of heat on a fusible link in the wire FLOAT: A valve that is opened and closed by the action of a float that rises and falls with water level. The float may be a ball attached to a lever or other mechanism HYDRAULIC: A valve that is opened and closed by hydraulic actuation LEVER: A valve that is opened and closed by the action of a lever rotating the gate within the valve. LOCKSHIELD: A valve that requires the use of a special lockshield key for opening and closing, the operating mechanism being protected by a shroud during normal operation. MOTORIZED: A valve that is opened and closed by the action of an electric motor on an actuator PNEUMATIC: A valve that is opened and closed by pneumatic actuation SOLENOID: A valve that is normally held open by a magnetic field in a coil acting on the gate but that is closed immediately if the electrical current generating the magnetic field is removed. SPRING: A valve that is normally held in position by the pressure of a spring on a plate but that may be caused to open if the pressure of the fluid is sufficient to overcome the spring pressure. THERMOSTATIC: A valve in which the ports are opened or closed to maintain a required predetermined temperature. WHEEL: A valve that is opened and closed by the action of a wheel moving the gate within the valve.
  | 弁操作: The method of valve operation where:弁操作方法は以下の通り： おもり(DROPWEIGHT)＝おもりを付けられたレバーが外される動作で閉まる弁　浮き(FLOAT)＝水位と共に上下する浮きの動作で開閉する弁。浮きはレバーに付けたボール又は他の機構　水力(HYDRAULIC)＝水力アクチュエータで開閉する弁　レバー(LEVER)＝弁内のゲートを回転させるレバーの動作で開閉する弁　ロックシールド(LOCKSHIELD)＝開閉のために特別のロックシールドキーの使用を要求する弁。操作機構は通常の操作の間は覆いで保護されている　電動化(MOTORIZED)＝アクチュエータに付けられた電動モータの動作で開閉する弁　空気圧(PNEUMATIC)＝圧縮空気で動くアクチュエータで開閉する弁　筒型コイル(SOLENOID)＝ゲートに付けられ作動しているコイルの磁界で通常は開に保たれている弁。しかし、もし磁界を発生している電流が消されたらただちに閉まる　ばね(SPRING)＝板に付けられたばねの圧力で、通常は位置を保たれている弁。しかし、もし流体の圧力が、ばねの圧力より十分大きければ開いてしまう。　自動温度調節(THERMOSTATIC)＝前もって決められた要求温度を維持するために、中のポートが開閉する弁　ハンドル(WHEEL)＝弁内のゲートを動かすハンドルの動作で開閉する弁

CONFIGUREDGATE: Screwdown valve in which the closing gate is shaped in a configured manner to have a more precise control of pressure and flow change across the valve. GLAND: Valve with a tapered seating, in which a rotatable plug is retained by means of a gland and gland packing. GLOBE: Screwdown valve that has a spherical body. LUBRICATEDPLUG: Plug valve in which a lubricant is injected under pressure between the plug face and the body. NEEDLE: Valve for regulating the flow in or from a pipe, in which a slender cone moves along the axis of flow to close against a fixed conical seat. PARALLELSLIDE: Screwdown valve that has a machined plate that slides in formed grooves to form a seal. PLUG: Valve that has a ported plug that can be turned relative to the body seat ports. WEDGEGATE: Screwdown valve that has a wedge shaped plate fitting into tapered guides to form a seal.
