Pentair Keystone Single Seat Valves F267J - F268J

Functional description

The Pentair Single Seat 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) as selected at time of order.

The mode can also be easily changed on site by simply inverting the actuator assembly. When air pressure is applied to the cylinder, the valve plug moves through its entire stroke changing from one state to the other. In the case of the F267J+ from open to closed or vice a versa, and the F268J+ changing the flow path from one direction to the other.

Pentair Single Seat Valves valves have only a few simple moving parts resulting in a very reliable valve in service.

Fields of application

Pentair Single Seat Valves are used to control process or CIP fluids. F267J+ for isolating, F268J+ for diverting or converging flows in the food processing, canneries, wineries, dairy, brewing, pharmaceutical, beverage and chemical industries. The valves can be manually operated or can be easily automated with the Figure 783 Easymind Electronic Control Top.

Working Principle

The F267J+ and F268J+ 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) as selected at time of order.

The mode can also be easily changed on site by simply inverting the actuator assembly. (See separate Installation, Operation and Maintenance Instructions for details). When air pressure is applied to the cylinder, the valve plug moves through its entire stroke changing from one state to the other. In the case of the F267J+ from open to closed or vice versa, and the F268J+ changing the flow path from one direction to the other. These valves have only a few simple moving parts resulting in a very reliable valve in service.

* (Option) 100 size valves can also be fitted with the Model 170 actuator as an option. This will boost the pressure holding power if required.

Manual Operator

The manual operator replaces the air driven actuator, and is used where variable control of flow is required or automation is not possible. Flow is fully adjustable throughout the entire stroke of the valve. The manual operator comes equipped with a visual position indicator and a locking device that can be engaged at any position. The lever crank allows quick and easy operation of the valve.

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.
