Unique 7000 - Manually Operated/Manually Regulating Valves

Simply Unique
Unique 7000 - Manually Operated/Manually Regulating Valves
Manually Operated and Manually Regulating Valves

General Information

The new generation that meets the highest demands of your process in terms of hygiene and safety. Unique Single Seat Valves are built on a well-proven, platform from an installed base of more than one million valves.

Application

The sanitary and flexible design of the manual operated Unique Single Seat Valve can be used in a wide range of applications , eg. as a shut-off valve with two or three ports or as a change-over valve with 3-5 ports.
The manual regulated Unique Single Seat Valve is a regulating valve used for manual control of pressure and flow.

Working principle

The valves permit gradual opening and the few and simple moving parts result in very reliable valves easy to dismantle. The plug can be fixed in the adjusted position with a lock screw. The valve is based on the modular platform of the Unique Single Seat Valve.

Standard Design

The manual operated valve can easily be converted to a pneumatic operated valve by replacing the crank mechanism with an Unique SSV actuator. The other parts are identical.

Sanitary Unique Single Seat Valve, pneumatic:

- Shut-off valve
- Change-over valve
- Reverse acting valve
- Aseptic valve
- Long stroke version

Kv-Factors

* optional
Kv = m3/h at a pressure drop of 1 bar.
Valve size Kv
1.5" 14*/44
2.5" 113
4.0" 250

For other pressure drops than 1 bar the flow can be calculated with the following formula:

Q = Cv x √Δp

Where
Q = Flow in m3/h.
Cv = See above.
Δ p = Pressure drop in bar over the valve.

Example:

Plug Kv 75

Q to be calculated at ∆p = 2 bar:
Q = 75 x √2 = 106 m3/h
or at 50% stroke:Q = 0.5 x 75 x √2 = 53 m3/h

Pressure drop/capacity diagram:

The plugs have linear characteristics. This means that a certain amount of throttling, by reducing the stroke, results in a proportional reduction of the flow if the pressure drop remains unchanged.
