Specifications

The pill valve is available in a butterfly or rotary valve version. Valve weights in Kg (without air motor)

DN	WW	WR	RR	WCWC	WCWR	RCRC
150/80	9,8	10,6	11	11,6	11,6	12
200/80	13,9	14,7	15,1	15,7	16,7	16,1

The inner rotor and outer vanes are operated using pneumatic actuators. The outer vanes are rotated 90° to open and close it. The inner rotor oscillates 180° to drip the feed product.

The feed rate in the trickle feeding stage is controlled using the frequency of oscillation

Works in conjunction with a balance – rapid flow with vanes open for most of the product, then changes to trickle feed for final weight adjustment

Very accurate dosing of the final total weight

Cleaning in place: no valve disassembly required

Disposal of process machines

Various body styles, including quick-release belt systems for quick cleaning (see sole valve and rotary valve catalogues)
