HYAF lined fluorine-plastic spread pneumatic tank bottom valve (Special corrosion protection cut-off valve)

HYAF fluorine plastic lined upward expansion pneumatic tank bottom valve is a special corrosion-resistant shut-off valve. The valve body inner wall and valve components in contact with the fluid are all high-pressure injection molded, lined with corrosion-resistant and aging resistant non-metallic F46, PFA, and can withstand almost all media (including concentrated nitric acid and aqua regia corrosion). It is mainly used at the bottom of various storage containers. Its smooth and streamlined valve body flow channel design, spherical single seat valve core type, is easy to flow media, and is widely used in industries such as polymerization reaction, chemical fiber, food, fermentation, etc. It is especially suitable for controlling acid, alkali corrosive media, toxic and volatile gases and liquids. For slurry and high-density fluid applications, it is also an ideal choice. When selecting this series of valves, it is necessary to consider the temperature, pressure, adhesion, corrosiveness and other conditions of the medium in the storage container. In order to maximize the satisfaction of different working conditions, in addition to the standard products provided by the samples, we can also provide non-standard design products according to the special requirements of users. The HY series PTFE tank bottom valve has two structural forms, HYAF is an upward expansion type and HYBF is a downward expansion type. Can be equipped with HA film type actuators and HV single acting cylinder type actuators. The leakage of the regulating valve complies with the GB/T4213-2008 standard.

 Product features:

1. The valve body flow channel and wall thickness adopt CAE structural strength analysis, to meet the minimum wall thickness design requirements and design strength, minimize weight and reduce cost, and high economy.

2, the valve body flow channel is smooth and streamlined, easy to medium flow,

3, the valve body and the valve components and the contact
