Product name:Stop valve with packing gland
Product introduction:
Globe valve to ANSI/ASME, with flange, steel casting A216 WCB, Trim 8 (Stellite/13% chrome steel) for classes 150/300/600, Trim 5 (Stellite/Stellite) for class 600, with cover flange, external spindle thread and clevis, graphite gland packing, stainless steel/graphite sealing gasket.
Application:
1. Boiler feed water
2. Conventional power plants
3. Petrochemical industry
4. Pipelines and oil storage tanks
5. Refinery equipment
6. Process technology
Advantages:
1. Long service life and high functional reliability of the gland due to the main shaft with calendered shaft.
2. Uniform compression of the packing rings due to the self-aligning two-piece gland follower.
3. High pressure of the gland follower and prevention of intermediate graphite gland ring extrusion gaps due to the graphite gland with sealing ring.
4. Reliable sealing and long service life due to the armored housing sealing surface and the robust conical sealing surface made of wear-resistant and corrosion-resistant material.
5. The standard back seal provides additional reliability and protection against blowout.
6. Numerous applications can be realized due to the non-ferrous metal-free spindle nut.
7. Reliable sealing due to the labyrinth cover seal on both sides. This prevents the sealing gasket from sagging.
8. Extended maintenance-free operation
9. Additional wear resistance due to armored overlay on the cone and seat ring.
10. Realized by integrated sealing surface.
