Parker Hannifin Corporation Flanged Products Introduction Parker Hannifin's response to the demand for reduction in leakage paths has been the combination of primary and secondary valves into one compact unit. The combining of piping and instrument valves into a single unit has benefitted various markets. Benefits Markets More compact design Offshore oil and gas platforms Reduced leakage paths Onshore terminals Reduced vibration and pipework stresses Chemical, petro-chemical, refining Weight saving Control panel manufacturers Reduced installation cost Process power industry Choice of designs LNG carriers Parker Hannifin can offer the unique combination of Double Block and Bleed valve systems together with integral fittings, both being designed and produced by one company.

3 Selection of this combination results in the elimination of taper thread connections and the need for thread sealant. For more information on leak path reductions and how to combine connections and valves into one unit, please contact us on 3. Parker Hannifin Corporation Flanged Products Primary, secondary and vent valve applications and installations Conventional installation Parker Pro-Bloc . Typically this will feature a branch-welded flange, Incorporates a body extending from a connected to a Primary ANSI class isolating valve of Ball, standard flange in a one-piece Gate, Globe or design. The outlet of the primary integral forged unit. Along the length valve will be converted to instrument standards and will of the extension it is possible to install include a secondary instrument needle valve together and consolidate primary, secondary with a Bleed valve.

4 A pressure gauge or transmitter will and Bleed valves. At the end of the then be installed downstream of the instrument valves. body extension a connection can be provided to suit any instrument, this connection could be a Parker A-LOK , CPI , pipe threaded NPT, BSPT, BSPP or pipe flange outlet. With Parker's Pro-Bloc a choice of four valve designs are offered, Ball, , Needle and Mini as a mixture or all of the same type. The Pro-Bloc . offers considerable space, weight and installation savings and improves safety factors through the reduction in connections. See page 12/13 for details. Typical heights 650mm 330mm 35/40 kgs 7 kgs Typical 4. Parker Hannifin Corporation Flanged Products Design codes Solutions All Parker Hannifin Double Block and Bleed Parker Hannifin offers the unique solution by designs comply with the following codes.

5 Incorporating primary and secondary valve ANSI/ASME (Design/material). systems into one complete Block . In addition ANSI/ASME (Threads). traditional instrument taper thread connections ANSI/ASME (Dimensions). can be totally eliminated resulting in systems API 607/BS6755 part 2 (Fire safety subject to being free of thread sealant debris specification). Parker Monoflange Parker's New Pro Valve This design is more compact than Pro-bloc Adds a different dimension to the compact adding to further space and weight saving designs currently available; conventional possibilities, primary, secondary and Bleed Double Block and Bleed installations feature a valves are assembled on the periphery of the pipe flange inlet bolted to a mating flange flange. The manifold body can incorporate both from the process line.

6 The new Pro Valve and instrument needle valves as a eliminates the need for these flanges having a mixture or all of the same type. Monoflanges are weldable connection and valve body forged in available from forged or bar stock material. the popular Weldolet style. Standard See page 10/11 for details. and instrument valves can be assembled into the body giving the same functions of conventional Double Block and Bleed Manifolds . See page 15 for details. 5.
