Pentair Südmo Hygienic Double Seal Valves F269J+

Pentair hygienic Double Seal Valves F269J+ J- series are used for product isolation, where safe mixproof separation of process and CIP fluids is required. Double Seat Valves offer a variety of options that allow monitoring and control of the valves through a PLC control system via the Easymind control unit.

The Pentair Double Seal Valves are operated by compressed air, via a linear pneumatic actuator, that can be supplied with or without spring return. The at-rest position of the valve, although normally closed (down position), can also be provided in the normally open (up position), this is determined by the actuator mode being either Spring Extend (SE) or Spring Retract (SR) respectively as selected at time of order. The mode can also be easily changed on site by simply inverting actuator assembly. When air pressure is applied to the cylinder, two small pneumatic normally open (NO) poppet valves, a leak detecting and a CIP valve instantly close and the main valve plug moves through its entire stroke changing the valve from the closed to open position.

When the air is removed or vented from the cylinders the main valve closes, following which the two smaller valves open, thereby venting and draining the leakage chamber to atmosphere. With the main valve in the closed position the leakage chamber can be flushed with water or CIP to clean away product residues. Whilst the valve is in the closed position, one side of the valve can be CIP cleaned while product remains on the opposite side fully protected from possible contamination by the double seals and leakage chamber.

Fields of application

The Pentair Double Seal Valves can be used to control process or CIP fluids in the food processing, canneries, wineries, dairy, brewing, pharmaceutical, beverage and chemical industries. These hygienic valves can be easily automated with the Easymind Electronic Control Top.

Recommended Seat Flushing CIP Flow/Velocity Information

With the main valve in the closed position, it is recommended the leakage chamber be flushed with water or CIP solutions to clean away any product residues after each valve operation. Also for the most effective clean, the main valve should be pulsed during entire systems cleaning cycle.

CIP flow rate: 3.5 – 4.0L/min at 1.5bar inlet pressure.
CIP velocity: 1.5m/sec (minimum)

Valve Type

Pentair Keystone Double Seal Valve F269J+ Valve Type

3-Position Actuator

The 3-position actuator can be used for an adjusted flow control at any position throughout the valve’s entire stroke. For example on dosing or filling to give optional full flow or partial flows, for topping up, or varying flow between product or CIP duties.

Booster Actuator

The booster actuator can be used where extra force is required to hold seal tightness under extra high line pressures, or for opening valves against high line pressures.

Position Sensors

Standard Ø18mm barrel type proximity sensors can be provided as a kit, complete with mounting bracket and sensor target.
