Electric PVDF ball valve needs to consider two temperatures: medium temperature and actuator ambient temperature

PVDF electric ball valve has two conditions: medium temperature and electric actuator environment temperature. The customer specifies the normal, cleaning, and seasonal temperatures separately, and then checks the valve body, seal, and actuator, without having one temperature to cover the entire range.

The liquid receiving side is a combination of material, pressure, and time

The valve body, sphere, and seal of PVDF jointly affect the applicability of the medium side. Temperature changes may alter the long-term pressure conditions of materials, and the maximum temperature and room temperature PN cannot be independently combined to ensure full temperature pressure. Please also specify the normal continuous temperature and short-term temperature peak, and consider the conditions of the cleaning solution. The specific parameters of Q941F-10F on site can be communicated, but the project still needs to correspond to the complete material combination of the finished product, and the resin material list will not replace the finished product rating.

The temperature near the actuator may not necessarily be equal to the meteorological temperature

The conduction of the valve body, insulation cover, adjacent equipment heat sources, and sunlight may alter the local environment of the electric actuator. The ventilation status of enclosed cabinets or spaces can also affect heat dissipation. Only recording the city weather cannot fully describe the installation location. The environmental conditions of the actuator should also be coordinated with the duty rating and action load, and the control module should not be assumed to withstand the temperature of the liquid just because the product is used for hot liquids.

Condensation and chemical atmosphere are additional conditions

Cold and hot cycles may cause condensation, and the external chemical atmosphere may corrode the shell, interface, and seal. The compatibility of PVDF does not represent the compatibility of all external accessories, and high protection level cannot replace chemical resistance data. The inquiry should be separated into a list of media and an environmental list, indicating humidity, flushing, sunlight, and corrosive gases, so that the valve body and electric actuator materials have separate basis.

Consider thermal displacement together with pipeline design

The temperature change of the valve body medium can also cause displacement of the pipe section and interface load, and the weight of the actuator may be involved in the force. Thermal environment, mechanical support, and contact pressure are related but different evaluations. The selection table should list the normal maximum medium temperature, environmental range, working pressure, sealing, operating frequency, and installation space separately. This way, it can be discovered that a certain component reaches the boundary first, rather than writing the entire machine as high-temperature resistant.

Corresponding products and selection entrance

Prepare two condition tables for the electric PVDF ball valve: one for medium and pressure temperature, and one for actuator environment and action load. Combining them to check the complete finished product can be more accurate than pursuing higher temperature resistance in a vague way.
