BRASS CHECK VALVES

Application

Watts Ocean's brass check valves prevent backflow of potable water with anunknown quality. The check valve's function and tightness can be tested withoutthe need for disassembly. Brass check valves can be used both in domestic andin other applications.

Fields of applicationLiquids potable water, cooling water, heating water, diesel, light fuel oil, petrolGasses compressed air, nitrogen

Operation

The pressure of the liquid flowing in presses the valve against the torpedo,creating an opening. The patented split valve stem guarantees motion-freeguidance between the valve and the torpedo. When the liquid pressure drops,the valve is closed according to the Lipseal sealing principle.

This Lipseal sealing principle works as follows:1. Valve open. Liquid pressure keeps the valve open.2. Initial closing. Without counter pressure, the valve pushes the rubber

diaphragm outward, already sealing the inlet.3. Total closure. The rubber diaphragm is pushed outward completely by

the valve. The counter pressure pushes the rubber diaphragm flush against the valve, thus sealing the inlet completely.

Other models

Refer to the table on page 5 for the various models.

1. Valve open. 2. Initial closing. 3. Total closure.

5Operation split valve stem

Under certain conditions, e.g. flushing the toilet atnight, vibrations can occur as a consequence ofthe valve stem being able to move sideways. Thesplit shape of the valve stem, however,guarantees maximum guidance. Vibrations areprevented by combining an optimum flow profileand a split valve stem.
