Service: Steam, water, oil , gas, air and chemicals
Shutoff: ANSI Class IV
Options:
- Double Bolting: increases the pressure rating of the valve and ensures a tight seal between the spring housing and the body for services with high inlet pressures
- High Pressure Spring Housing: The HP option is an elongated spring housing that features a
large spring for high pressure setpoints (up to 450 psi/31bar) - Handwheel: the H option is a handwheel that is mounted on the adjusting screw to allow for easy setpoint changes
- Exotic Alloys: where service conditions dictate the use of specialty materials, the Mark 60 Series can be produced with bodies, trim and seats in Monel, Alloy 20, Hastelloy B, Hastelloy C, Titanium and others
- GP Option: grain processing modif ication for starch cookers and other viscous services. Available on Stain less Steel valves in 1/4″ – 2″ sizes only (DN8 – DN50)
- Cryogenic Service: CR option is a special spring housing for use if valve is in cryogenic service
Rangeability:
- Equal percentage or equal-linear : 60:1
- Linear: 30: 1
Low Flow Cv’s: reduced Cv’s (Kv’s) are available . Cv (Kv) ratings of smaller sized valves can be supplied in a larger valve size
