First, the three-way valve Product Overview Haichuan Shanghai Valve Co., Ltd. of Q44F, Q45F ball valve, can be divided into L-shaped and T-shaped, L-shaped (Q44F) ball valve for switching the flow of media, make mutually perpendicular The two-channel connection; T-shaped (Q45F) ball valve for media streaming, confluence and flow switch. T-shaped links can make three channels communicate with each other or to one of the two passage. Features: 1, the three-way ball valve in the structure of the integrated structure, 4 seat sealing surface type, small flange connection, high reliability, design and implementation of a lightweight. 2, three balls wick T-shaped and L-shaped, long life, high flow capacity, small resistance. 3, ball points by acting single and double acting two types, single-action feature is the power source in the event of failure, the ball will be in the state control system requirements. Applicable scene: Way ball Q44F, Q45F widely used in water, oil, gas, nitric acid, acetic acid class a variety of media.
