Azbil VST/VAM for Minimal flow control valve top-oriented single-seat regulator for heavy load. Azbil VST/VAM for Minimal flow control valve body has a compact structure, S-shaped fluid channel, small pressure loss, strong flow capacity, wide adjustable range, high accuracy of flow characteristics. The top guide area is large, with strong vibration resistance. The turn-off performance meets IEC or JIS standards. Actuator using simple, miniaturized multi-spring film type, compact structure, large output force.
Model Azbil VST/VAM for Minimal flow control valve small shape high-performance top oriented regulating valve is widely used in high temperature, low temperature, high-pressure fluid pipeline, can achieve reliable control, with high turn-off performance. The regulating valve meets the functional safety standard (IEC61508).
Model Azbil VST/VAM for Minimal flow control valve has the following features:
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.
Cage-type single-seat valves with excellent anti-cavitation performance are available for severe service in high temperature and high differential pressure.
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.
Metal seat tight shutoff (class V) and soft seat tight shutoff (class VI) are available.
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 is achieved by a combination of wide rangeability and a smart valve positioner.
