The NDL (Non Dead Leg T Valve) diaphragm valves, manually or pneumatically operated, are specially designed for use on aseptic processes in the pharmaceutical industry. The valves are widely used at points of use in the loops of purified water (PW) or water for injections (WFI). Operating principle   The diaphragm provides the body seal as well as the seat seal. There are no paths to the outside environment and, as such, the valve is suitable for aseptic processes. When the valve is being closed, a pressure pad which supports the diaphragm moves towards the sealing face on the body. As the pressure plate moves, the diaphragm flexes and is forced down onto the seat area in the centre of the body, thus, closing off the flow path through the body.The valve can be actuated either manually or pneumatically and controlled by control units and solenoid valves.A standard diaphragm valve is used to shut the flow of a line, an NDL type valve shuts only one outlet of the main line.   Design and features   Comparing with a traditional diaphragm valve, the dead leg of an NDL valve is reduced to a minimum due to the design of the valve, and the pharmaceutical normatives like ASME BPE prioritise this condition.

Diaphragm Digital Control Valve is an electrically actuated, hydraulically operated multi-function control valve. It can be used for local as well as remote controlled batching operations with electronic batch controller. The valve also offers an in-built flow governing function   DESIGN FEATURES   Precision multi-stage opening and closing Fail-safe design Low pressure drop Bubble-tight seat design Flow rate control PRINCIPLE OF OPERATION   The Diaphragm Digital Control Valve basically consists of a diaphragm operated main valve and two solenoid valves. Normally open (NO) solenoid connects the valve cover chamber to the upstream pressure, whereas normally closed (NC) solenoid connects the valve cover chamber to the downstream pressure. When the Diaphragm Digital Control Valve is used with an electronic batch controller, it can be digitally controlled by operating the solenoid valves through any of these three stages : when NO and NC solenoids are energized, the valve opens gradually. when NC solenoid is de-energized (keeping NO solenoid energized), the valve locks at its current position. when NO and NC solenoids are de-energized, the valve closes gradually. The operation of the valve is simple and is explained below. The total batch quantity delivered and controlled through the valve is divided into 7 stages (Refer graph) for the purpose of convenience. Initially both NO and NC solenoid valves are in de-energized condition. The NO valve applies high upstream pressure on the diaphragm, whereas the NC valve prevents this pressure from getting drained to the downstream side. The valve remains close as a result of this. Stage 1Both NO and NC solenoids are energized. NO valve now restricts the high upstream pressure from entering into the cover chamber. NC valve permits the pressure above the diaphragm to vent to the low downstream pressure. This creates a differential pressure across the diaphragm, the high upstream pressure acting from below the diaphragm opens the main valve and allows the flow to start through the valve. Stage 2As the flow rate reaches predefined value (set in the batch controller as “Low Flow Start”) the NC valve is de-energized. This prevents further draining of the chamber and locks the valve at this flow rate. Initial delivery at slow speed avoids splashing of product and also avoids the generation of static charge. Stage 3When sufficient quantity is delivered at the slow speed, the NC valve is energized again. This allows further draining of the chamber and hence increases the flow. Stage 4When the flow reaches to the maximum level (set in the batch controller), the NC solenoid is de-energized. This maintains the constant high flow rate for the remaining batch. During this stage, the flow rate control is done by the batch controller. When a number of flow meters are connected to the same pump, stopping (or starting) one or more meters increases (or decreases) the flow rate at the remaining meters. When the flow rate increases, the NO solenoid is energized momentarily. This injects some high pressure in the cover chamber and makes the valve to throttle in order to maintain the set flow rate. If the flow rate decreases, the NC solenoid is energized momentarily. This allows slight draining of the chamber and allows the valve to open further in order to maintain the set flow rate. Stage 5At the end of the batch, the NO solenoid is de-energized. This injects high upstream pressure into the cover chamber and throttles the valve. Stage 6When the valve throttles sufficiently to achieve the predefined slow closing flow rate (set in the batch controller), the NO solenoid is energized. This maintains the uniform flow rate. Stage 7When the batch quantity is delivered, the NO solenoid is de-energized. (NC solenoid is already de-energized.) This applies high upstream pressure into the cover chamber, which makes the main valve to close completely to achieve bubble-tight shut-off. Note: The number of stages during opening and closing are programmed in the batch controller and can be as many as desired. One stage during opening and two during closing are recommended. Caution: Sufficient pumping flow rate should be available to achieve the flow parameters set in the electronic batch controller. In the absence of this, there are chances of delayed response in closure, resulting in valve over-run.
