Pentair Keystone Single Seat Tank Bottom Valve F273J+

Functional Description

Pentair Single Seat Tank Bottom Valves are operated by compressed air, via a linear pneumatic actuator or manual operator. The at-rest position of the valve when actuator is fitted with a spring, although normally closed, can also be provided in the normally open position, this is determined by both the plug configuration and the actuator mode combination being used and as selected at time of order. I.E. Spring Extend (SE) actuator with an Int. plug type will result in a Normally Closed (NC) valve, therefore SE + Ext.= NO, Spring Retract (SR) actuator with an Int. plug type will result in a Normally Open (NO) valve, therefore SR + Ext.= NC 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 single seat tank bottom valve from open to closed. These valves have only a few simple moving parts resulting in a very reliable valve in service.

Fields of application

Pentair Single Seat Tank Bottom Valves are used to control process or CIP fluids exiting and entering tanks or vessels in the food processing, canneries, wineries, dairy, brewing, pharmaceutical, beverage and chemical industries.

Working Principle

The F273J+ 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 when actuator is fitted with a spring, although normally closed, can also be provided in the normally open position, this is determined by both the plug configuration and the actuator mode combination being used and as selected at time of order.

I.E. Spring Extend (SE) actuator with an Int. plug type will result in a Normally Closed (NC) valve, therefore SE + Ext.= NO, Spring Retract (SR) actuator with an Int. plug type will result in a Normally Open (NO) valve, therefore SR + Ext.= NC 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 F273J+ from open to closed. 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.
