HVF : Tassalini Valves

Designed and built to meet the exacting requirements of the 3-A Standard the Diaphragm Valve has become the valve of choice in the Fine Chemical, Cosmetic and Bio-Pharmaceutical Industries.

The valve body is Hot Forged and Solution Heat Treated from AISI 316L SS before being machined and polished. The valve design ensures that the diaphragm is pulled away from the Weir Shaped Sealing Face allowing the product a clear and unobstructed patch through the valve. Viscous products such as slurries that would normally clog another valve design are kept moving and pass through the valve, while flow continues.

The valve operating mechanism is top mounted which allows for easy access for maintenance and repair with the valve remaining in situ. The valve is also suitable for flow control and can be operated both manually, pneumatically or electrically.

The simple valve design allows many design variations and has led to a whole range of sampling options and branch valve arrays to develop from the original straight through 2/2 Way principle.

Diaphragm materials are also tightly regulated to meet the exacting demands of the FDA, CFR and USP classifications.

Maximum working pressure:  7 Bar.

The standard finish is 150 grit with higher finishes at 240 Grit (0.51µM Ra) and 400 Grit (0.38µM Ra) Electro-Polished being available on request.
