Single Port Control Valve

Single port control valves are designed for heavy duty service. The compact valve body, having a S-shape flow passage that features low pressure loss, allows a large flow capacity, range ability, and high accuracy flow characteristics. The valve plug is highly vibration-resistant as it is held by a top guide section which has a large sliding area. The flow shut-off performance complies with the IEC or JIS Standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs.

Single-seat control valves are widely applicable for reliable control, with high shut-off performance, in high or low temperature, high pressure process lines.

Design Features

HIGH PERFORMANCE DESIGN

Our single port globe control valve are engineered to handle the most demanding process conditions and exceeds the capabilities of comparable designs, provides some key advantage versus typical design:

A variety flow capacities can be selected for lower and larger flow process condiftions
Higher Pressure drop capabilities
Tighter shut-off ratings
Reduced actuator size and thrust requirements

WIDE APPLICATION RANGE

The single port control valves provide high flow capacities combined with low pressure, high pressure or high temperature applications.

MAXIMUM RELIABILITY

Specification and selection of the best solution for any application is simplified with the standard design options and materials available in the sing port globe control valves. the valves have over 30 years of successful field experience in sugar and starch process industries.

VARIOUS TRIM SOLUTIONS

The valves is available with a variety of trim designs and materials to meet different flow capacities and characteristic requirements, it provides high capacity or high precision type contoured plugs, equal percentage or linear characteristics, soft or metal seats.
