Screw Adjustment

Valve can be adjusted with an Allen wrench. Lock nut included to maintain desired setting after adjustment. This is the most common adjustment option available on most Vatac products.

Knob Adjustment

An aluminum knob is added to the standard screw adjustment. A lock knob is provided to help maintain the desired setting after adjustment. Vatac offers knob conversion kits for most flow control valves. For kit numbers consult the individual valve pages.

Fixed Style

In most cases, the Fixed Style product is a screw adjustable product with a steel collet threaded over the adjustment. These valves are preset at the factory. Should the valve need to adjusted, the star washer and aluminum plate can be removed from the top of the assembly exposing the adjustment.

Flow Control Valve

A float control valve maintains a preset water level in a reservoir or a water tank. In its simplest form a float valve is fitted with a float designed to control the top water level in the tank. A dual level float can be fitted to control the level between top and bottom levels. Float control valves can be remotely operated with an addition of a solenoid or a hydraulic relay.

Typical Applications

A top level float valve is typically used where water tanks are required to be full and where the tank is not filled up by a dedicated pump, a dual level float can be fitted in order to minimise pump starts and stops.

Tamper Resistant

The tamper resistant option is a screw adjustable valve with a steel cap installed to conceal the adjustment. The cap is designed so the internal edges clamp into the groove of the valve adapter. Once the cap is installed, it cannot be removed without damaging the cap and the valve. When a valve is ordered with the tamper resistant option, it will be preset at the factory, and the cap will be included in a separate plastic bag to allow for fine tuning at the customer site. Parker offers tamper resistant cap conversion kits for most flow control valves. For kit numbers consult the individual valve pages.
