JPE two valve calibration manifold 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.
* Features :

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 media.
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), 6000psig at 200℉ (414bar at 93℃ )
7. Pressure rating at max. temp.: PTFE - 4130psig at 450℉ (284bar at 232℃) and Grafoil - 1500psig at 1000℉ (103bar at 537℃).
8. The orifice size: 0.156 inch (4.0mm).
