A wide range of available materials

Products can be provided to meet a variety of body material specifications, such as: carbon steel, which is generally used with water, steam, and fuel oil; highly corrosion resistant stainless steel, which is essential for controlling corrosive fluids; and resin.

Severe service applications

Cage-type single-seat valves with excellent anti-cavitation performance are available for severe service in high temperature and high differential pressure.

Control of highly viscous fluids, slurry, and coagulable fluids

Control of various fluids is enabled by hardening of the valve interior, self-washing structure (optional), and steam jacketing (optional) to prevent coagulation by keeping the valve body hot.

Excellent seat leakage performance

Metal seat tight shutoff (class V) and soft seat tight shutoff (class VI) are available.

Excellent external leakage prevention performance

A bellows seal can be added to valve stems. Increasingly sought-after specifications for gland packings can be applied to comply with fugitive emissions regulations for volatile organic compounds.

High control performance

High control performance is achieved by a combination of wide rangeability and a smart valve positioner.
