Pneumatic keep warm ball valve
详情介绍
product description
Summary:
This product has good heat preservation and cold protection characteristics, and the valve size is the same as the pipe diameter, and can effectively reduce the medium heat loss in the pipeline. It is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport high viscosity media which will solidify at room temperature.
Due to the use of integral structure, so the insulation ball valve than the general ball valve which is smaller, lighter weight, and no leakage, good sealing performance, jacket using carbon steel pipe welding than casting more pressure firm.

Ordering information
1. Please provide detailed caliber specification, delivery place and delivery time when ordering.
2, according to the needs of the pipeline, decided to choose reciprocating (two switch type) or spring return type (usually closed or often open).
3, optional control accessories :(1) single solenoid valve (normally closed or normally open), (2) double solenoid valve (switch type), (3) valve position switch back sensor, (4) air source processing triplets. Special use environment (inflammable and explosive occasions), how to choose the explosion-proof type.
