CS015 DN10
The Watts check valve type CS015 is the latest generation of check valves.Not only do these check valves operate ideally, they also offer added advantages:- identical contours in open and closed position (stem of valve doesn't protrude);- variable outlet system, facing side or rear side.The innovative use of materials in these valves renders them more resistant to both chemicals and high temperatures. The CS is also more compact than conventional check valves, and therefore easier to fit!

The Watts snap-in valve type IN015 is a compact and therefore easy to install check valve. The advantage for OEM applications is, that in case of a side-connection in the housing, the O-ring can be mounted first and secondly the check valve itself. This way the O-ring will not be damaged by the sharp edges of the side-connection.This check valve will meet all quality requirements.Its advantages are yours.

IN032 DN32
The Watts snap-in valve type IN032 is a compact and therefore easy to install check valve. The advantage for OEM applications is, that in case of a side-connection in the housing, the O-ring can be mounted first and secondly the check valve itself. This way the O-ring will not be damaged by the sharp edges of the side-connection. This check valve will meet all quality requirements.Its advantages are yours.

The TO015 is specially designed for hydraulic safety groups that are fitted to the cold water supply of storage water heaters. This special valve is tested according to the EN1487and will stand a maximum half hour of heavy treatment with saturated steam up to 180°C during calamities. Due to the PPS material, the TO015 valve will keep its form and function. The lip-seal is mounted in such a way that it will survive the passage of high temperature steam during this simulated calamity.

Auxiliary mounting tools
In order to achieve a perfectly leaktight check valve construction, it is of crucial importance that mounting dimensions are respected.
On each check valve data sheet, you will find the required mounting dimensions to be created in the housing to the check valve.
In order to avoid any damage of the check valves and O-rings it is very important that check valves are mounted in the correct way.
To support positioning and mounting in the right way Watts Industries produced a mounting tool for every check valve. The dimensions of the tools are given in the data sheet below.
When an approved Watts check valve is built in in accordance with the mounting dimensions as given on the relevant check valve data sheet and when the proper auxiliary tools are used, Watts Industries ensures a check valve performance that will last for many years.
