The ChargePoint valve is a suitable product transfer solution for many reactor charging applications including Buffer prep, Bulk Powder Additions and Seed Charging.

The problem

For running a process under pressure or charging / dispensing under pressure, a split butterfly valve requires a pressure rated characteristic in order to provide the required level of pressure and ultimately, containment. In order to achieve these pressure and containment levels many split valves rely on the disc as the pressure seal. There are three problems with this method:
1. The design can only be used for sealing the process under pressure and not for charging / dispensing i.e. operating the valve under pressure.
2. With this method discs are thicker when compared to non-pressure rated valves. The larger disc cross section impedes product flow during the non-pressure powder transfer.
3. With larger valves the thicker discs increase friction on the sealing surface making manual operation difficult and increasing costs for necessary actuation.

The ChargePoint solution

The Pressure Rated ChargePoint does not rely on the disc to achieve pressure rating.
• For running the process under pressure the ChargePoint utilises a plug with o-ring seal to maintain pressure and containment.
• The valve can be operated under pressure in charging and dispensing applications. This is achieved by an o-ring seal on the Passive to maintain pressure and containment.
• The disc profile is not thicker than the standard ChargePoint resulting in the same level of good powder flow. There is also therefore no increases in sealing friction making manual operation easy.
• Eliminates requirement for actuation therefore saves cost and space.
