This valve is designed to inject water at the reactor dome for washing the reactor walls after each reaction. The rinsing operation needs to be optimised to suit the product being manufactured and the shape and size of the reactor. It is usually best to install two rinse valves opposite each other in the reactor dome to provide this optimisation. We provide two types of valve:
Rinse valve with non-rotating piston :
The piston movement is restricted to the axial direction. Provides overall rinsing of the reactor dome, with the liquid then flowing down to wash the reactor walls. This type of valve is best in reactors converting chemicals that do not stick.
Rinse valve with rotating piston :
The piston moves axially then rotates. The service life of the sealing rings is thus optimised. This type of valve is especially suited to reactors requiring active rinsing. The spray force comes into direct contact with the whole of the reactor walls. The rotary movement ensures a constant spray force is applied to each point of contact.
