Two Valve Manifold Calibration Manifold Needle Valve Manifolds Free - Swiveling Type Flange Type and Block Type
1 . Bonnet lock pins prevent accidental loosening
2 . Free - swiveling ball end stem ( metal seat , std ) assure bubble tight valve closure without seat galling . The special hardened ball seat is ideal for both gas and liquid service
3 . All stem packing is located below the stem threads prevent galling , corrosion and contamination by the process medias .
4 . The packing is adjustable with less possibility of bonnet / body leaks .
5 . Full back - seated bonnets prevent accidental stem removal and blowout . Unique design minimizes emissions while offering easy access to the packing .
6 . Max pressure rating ( metal seated ) . 6000 PSIG at 200 ℉ (414 barg at 93 ℃ )
7 . Pressure rating at max . temp . : PTFE - 4130 psig at 450 ℉ ( 284bar at 232 ℃ ) and Grafoil - 1500 psig at 1000 ℉ ( 103bar at 537 ℃ ) .
8 . The orifice size : 0 . 156 inch ( 4 . 0 mm )

Block Type
Two valve calibration mainfold provides an economical and convenient method of blocking , bleeding and calibrating pressure instruments . The block type ( R type ) may be mounted rigidly to a mounting bracket , providing a safe isolation valve and the single flanged type ( T Type ) is directly mounted while reducing the number of fittings and space required for installation .
