Specialist Valves for Hygienic and Sanitary Pigging

Unique, Easily Cleaned Hygienic Ball Valve System

The Inflatable Seal Ball Valve (ISBV ) has been specially designed and developed for use in sanitary and hygienic pigging applications.  Sometimes referred to as a Clean In Place or “CIP-able” ball valve,  it incorporates unique inflatable seal technology and has many benefits over a regular ball valve.

CIP and pigging go hand in hand. However, when it comes to valves, the ball in a regular valve has constant contact with one or more seals. This poses problems when wanting to clean the valve as it makes cleaning the cavity near impossible. That’s where HPS inflatable seal technology offers a major advantage.

Clean In Place

The Inflatable Seal Sanitary Ball Valve, as the name suggests, has an Inflatable Seal. This seal can be inflated and deflated as required. Once the seal has been inflated it acts as any other seal would, making contact with the ball and not allowing product to pass. When ready to clean the valve, the seals are deflated. This means the seals are no longer in contact with the ball and allowing liquid to enter the valves cavity and clean previously unreachable areas.

There are two variations of the Inflatable Seal Ball Valve:

• The 90 degree, Two position ISBV. This valve has two positions, open and closed. It can be used as Line or Tank Isolation valves in hygienic applications that require uninterrupted product flow or they can be used in combination with a pig housing to create a launch or receive unit.

• The 120 degree ISBV. This valve has three ports and can utilise all three of them using an electric actuator or two of them by using a pneumatic actuator. When using this valve in pigging it negates the need for a traditional two valve ‘T’ launch arrangement.
