Union Insert Check Valve Style – UV

Description

The Union Insert (UV) valve is the threaded pipe counterpart of the Flange Insert Valve. Designed to be inserted into most standard and hammer type ground joint unions, it provides the simplest and most economical way to install a check valve in a threaded pipe system. A check valve may be installed anywhere in the system where there is a union. The valve works equally well in either a horizontal or vertical position with proper spring selection. Each Union Insert Valve is furnished with a metal tag, which is quickly attached to the union. This provides a permanent visual notification that the union contains a check valve.
Bore of union must be equal to I.D. of schedule 40 pipe. Use ground joint unions with 45 degree seats only (union not included).

PED Compliance Statement: Due to the unique “insert” design of our 3S, SC, CB, TC, SI, & UV, style check valves, they do not constitute an “identifiable pressure bearing housing” as defined in PED Guideline 1/8. These styles must be installed into either ferrules or fittings to create a pressure bearing housing. Instead, they are classified as “components of pressure equipment” as defined in PED Guideline 1/8. As a result, these valves can be sold in the European Community and no CE Mark is required.

In addition applications where the maximum allowed operating pressure is 0.5 bar (7.2 psi) or less, do not fall under the PED, regardless of the valve style.
