Lined Ball Valve Features and operation methods of fluorine ptfe lined ball valve

Fluorine pfa lined ball valves have been used in anti-corrosion pipelines for many years. High-quality materials and advanced manufacturing processes are the quality assurance of fluorine pfa lined valves products. Since the company introduced and studied fluorine ptfe lined ball valve manufacturer technology, after years of unremitting efforts by engineering and technical personnel, it has successfully developed integral molded fluorine pfa lined ball valves manufacturers products. The main features are as follows:

1) High operating temperature: Under strong corrosive media conditions, it can meet the operating temperature range of -60℃~150℃. Within this temperature range (except molten alkali metals, elemental fluorine and aromatic hydrocarbons), it can meet all chemical media.

2) Vacuum resistance: In the range of -60℃~150℃, it can be used under vacuum conditions. In chemical production, due to cooling, longitudinal discharge, asynchronous operation of pumps and valves, local vacuum states are often caused.

3) High pressure resistance: Within the temperature range, it can withstand an operating pressure of up to 3MPA.

4) Anti-permeability: Select high-quality resin and process it into a high-density, sufficiently thick PTFE lining layer through advanced lining technology, so that the product has excellent anti-permeability.

5) The overall molded sintering process lining solves the problem of steel-fluorine cold and hot expansion and contraction, so that it can achieve synchronous expansion and contraction.

6) The fluorine pfa ball valve adopts standardized dimensions, especially the pipes and pipe fittings used in chemical pipelines have strong interchangeability, which provides great convenience for installation and spare parts.

Operation method of fluorine pfa lined check valve:

1) The opening and closing direction of the fluorine teflon lined ball valve during operation should be closed clockwise.

2) Since the fluorine ptfe lined valve in the pipeline network is often opened and closed manually, the number of opening and closing turns should not be too many, that is, the large diameter valve should also be within 200-600 turns.

3) In order to facilitate one person's opening and closing operation, the maximum opening and closing torque should be 240N-m under pipeline working pressure conditions.

4) The opening and closing operation end of the fluorine teflon lined valves should be square tenon, with standardized size and facing the ground, so that people can operate directly from the ground. Fluorine ptfe lined ball check valve with wheel discs are not suitable for underground pipe networks.

5) Fluorine fep lined ball valve opening and closing degree display disk:

① The scale line of the opening and closing degree of the fluorine fep lined valve should be cast on the gearbox cover or the outer shell of the display disk after the direction is changed, facing the ground, and the scale line should be brushed with fluorescent powder for eye-catching display;

② The material of the indicator dial needle can be stainless steel plate under good management, otherwise it is painted steel plate, do not use aluminum skin;

③ The indicator dial needle is eye-catching and firmly fixed. Once the switch is adjusted accurately, it should be locked with rivets.
