Valves

Valves that have ratings for use in hazardous locations. Some models of stainless steel ball valves. Applications include gas or liquid flow control and mixing or diverting liquids and gases.

Ball Ball valves have ratings for use in hazardous locations. Features a blowout proof stem (added safety), reinforced PTFE seats and seals for longer life. The actuator has 2 supply ports with 1 driving the valve open and the other driving it closed. Actuators feature thermal overload protection and permanently lubricated gear train. View More

Globe

Globe valves are linear motion valves for flow control of gases, liquids, and steam. Models are pneumatic actuated and economical valves. Coupled with the high flow capacity, the Hi-Flow™ control valve maintains a wide rangeability of 50:1. A few models have metal-to-metal seating that ensures excellent flow control and shut-off service.

Pressure Transducers

A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. Pressure transducers are used in many control and monitoring applications such as flow, air speed, level, pump systems or altitude.

Questions

Question

Hi-Flow™ control valves call out ANSI B16.104 Class IV flow leakage. What does this mean?

Answer

ANSI B16.104 is a testing specification for control valves. This specification has actually been superseded by ANSI/FCI 70-2 Class IV. The class IV designation defines the allowable amount of leakage through the valve seat in the closed position. Class IV allows for .01 percent of the rated flow (Cv), to pass through the seat. Class IV is common for metal to metal seated valves.

Question

What if I need parts for my Hi-Flow™ control valve?

Answer

Many Hi-Flow™ valves have been in service for 15+ years with all original parts. However, since Hi-Flow™ valves are commonly used in steam service, a severe application, some parts may wear over time. Unlike other control valves, Hi-Flow™ valves are designed with removable seat rings making repair or replacement of components an option. Although all parts are available, you will probably never need more than a seat ring, plug assembly, and stem packing to have a valve that is like new.
