ISOLATOR 2.0

Metal-seated severe service ball valves for low pressure applications

ASME 150 / 300 / 600 Standard Class: Designed for absolute isolation in low pressures and temperatures

ISOLATOR 2.0 is a metal-seated, bi-directional floating ball valve for absolute isolation in specific mining, refining, chemical/petrochemical, power generation and pulp & paper applications. This ASME 150-600 Class valve withstands temperatures to 1,000° F, and its durable materials of construction and proven coatings reflect its lineage of a longer life cycle over time.

Available in sizes 1/2 to 12 inch and in materials of construction that will suit your application.

• Features & Benefits
• Applications
• Downloads

1

CloseFloating ball design

• Rotating ball does not cause turbulent redirection or displacement of process fluid in the flowstream, resulting in less valve stress
• Straight-through full bore path protects sealing surfaces and packing area from particulate erosion
• Metal seats wipe sealing surface of ball clean during operation preventing solids build-up and clogging

2

ClosePressure-energized sealing

• Belleville spring in upstream provides constant contact between ball and seat for absolute shut-off and lower operating torque 
• Allows resilience during thermal expansion of trim; no graphite seat gaskets

3

CloseMatched ball and seats

• Ball and seat sets provide 100% sealing contact for absolute isolation and dimensional thermal expansion
• Mate lapping behind seat provides tight sealing
• Optimum seat face diameter allows for lower torque without sealing compromise

4

CloseIndependent replaceable seatsMinimizes maintenance and repair costs

5

CloseBlowout-proof stem design

• One piece design meets industry safety standards
• High strength alloy construction
• Thicker, more robust stem tang eliminates failure inside valve

6

ClosePacking boxHardened inner steam seal and graphite rings prevent stem packing leaks and risk of fugitive emissions

7

CloseForged body / end connections

• Greater wall thickness in critical areas provides longer valve life
• Available as raised face flanged, socketweld and buttweld

8

CloseLive-loaded springsBelleville washers and gland flange leaf-spring action provide constant pressure on packing
