Test the operating mechanism process of PTFE lined valve products

With the advancement of technology, the valve manufacturing industry is also developing rapidly. For the best-selling products in the current market PTFE lined valve The types of products inside are also diverse, just like Fluorine lined DC globe valve and check valve Wait a series. Of course, in the face of numerous valve products, what aspects should we choose suitable products from?

Today, we will explain the operating mechanism of PTFE lined valves. Firstly, the opening and closing direction of PTFE lined valves should always be clockwise. Due to the frequent manual opening and closing of PTFE lined valves in the pipeline network, the opening and closing speed should not be too high, even for large-diameter PTFE lined valves, it should be within 200-600 revolutions. For the convenience of one person's opening and closing operation, under the pressure of the pipeline worker, the larger opening and closing torque should be 240mm. The opening and closing operation end of the PTFE lined valve should be square tenon, standardized in size, and facing the ground, so that people can directly operate it from the ground. Fluorine lined valves with discs are not suitable for underground pipelines. If the PTFE lined valve is buried deep and the distance between the operating mechanism and display panel and the ground is ≥ 1.5m, an extension rod facility should be installed and firmly fixed for people to observe and operate from the ground. That is to say, the opening and closing operation of fluorine lined valves in the pipeline network is not suitable for underground operations.
