For safe repeata le
relia le and performance
1. Positive handle retention design featuring broached s uare engagement positioned by thread locked grub screw.
2. a r
Ergonomically designed for ease of operation. Anti-tamper and lockable devices can be supplied for on site retro-fit.
4. land packing ad uster
For maximum packing stability and performance, simple and easily ad ustable for gland wear compensation.
6. alve onnet
Standard construction for maximum pressure rating with replaceable bonnet sealing washer arrangement.
8. hrust ush
Anti rotational ad ustor bush ensures uniform packing compression, maximising pressure tight sealing and limiting cold flow passages.
10. onnet/ od washer
Annealed sealing washer to ensure complete atmospheric leakage and allowing on site retro­fit of bonnets with 100 re-sealing assurance.
3. ust C ap
This has a dual purpose, preventing air born debris from contaminating the operating spindle thread and providing colour coded functional identification. Isolate (BLUE).
5. land ad uster lock nut
A secure anti vibration locking mechanism to prevent inadvertent gland ad uster loosening.
7. nti lowout s pindle
Designed for low tor ue operation with high uality micro mirror stem finish for positive gland sealing.
9. land packing ad usta le
Chevron effect dual piece gland packing to provide maximum sealing area contact with minimum gland ad ustment.
11. pindle t i p
Self centering, non-rotational tip gives successive positive bubble tight shut off assuring the user of leakage free performance and downstream functional safety.
