Frequently Ask Questions
A Jacketed Discharge Valve is a vessel-bottom discharge valve equipped with a jacket around the valve body. A heating or cooling medium circulates through the jacket to maintain the temperature of the process material during discharge.
Its primary advantage is temperature control around the discharge area, especially for products that become difficult to discharge when they cool.
It can help reduce product retention by providing an efficient bottom discharge arrangement, particularly when properly installed at the lowest point of the vessel.
The jacket helps prevent the product from:
Solidifying
Crystallizing
Becoming excessively viscous
Blocking the discharge passage
It can also help maintain a consistent discharge temperature.
Alis Valves is a Jacketed Discharge Valve manufacturer and supplier in India, providing discharge solutions for chemical, pharmaceutical, API, resin, polymer, food and specialty-process industries where maintaining product temperature is important for reliable vessel emptying.
It can facilitate maximum practical vessel drainage, but actual drainability depends on:
Vessel geometry
Outlet location
Product viscosity
Valve design
Installation arrangement
