labora t or y ser vice fixtures

Provincial Lab Systems offers a wide selection of valves for use in the laboratory. The selection of a valve
for any particular application depends upon many factors, including the working pressure of the service,
the degree of metering or control desired. This Valve Selection Guide is presented to assist in selecting the
most appropriate valve for any application. All fixtures meet CSA standards and our standard product line
is designed and manufactured to meet or exceed industry standards, including SEFA 7-1996
“Recommended Practice for Laboratory and Hospital Fixtures.
Provincial Lab Systems cannot be responsible for the results obtained from using any particular valve in
any particular application. In particular, reference must be made to applicable plumbing and piping codes,
life safety standards and project specifications when selecting valves.
