Features
& Benefits - Single trim for all services provides full capacity
at 10% over- pressure for liquid, steam or vapor applications without additional
parts.
- Reversible disc provides a spare part in every valve.
- Nozzle
threads at top ensure better nozzle/body alignment and reduce maintenance effort.
Nozzle threads at top ensure better nozzle/body alignment and reduce maintenance
effort.
- Disc retention by ring eliminates potential of thread corrosion
and need for special maintenance tool.
- Standard Inconel® 625 Bellows
offers better corrosion resistance than 316L SS at no extra cost.
- Springs
within a pressure class and orifice size are designed with a fixed I.D. to eliminate
the need to custom machine steps for each spring.
- Identical nozzle ring
for each orifice size regardless of pressure range or seat design reduces parts
variations, except in RB Series F orifice.
- In the soft seat option, the
spring load is applied directly to the metal seat, increasing service life of
the O-ring. The soft seat disc retains the metal seat on its reversible side.
