General
JPLS Small-Port Single Seated Control Valves with a compact valve body and an S-shape flow way features with low pressure loss, large flow capacity, wide range ability and high-precision flow characteristics. The compact size and large output force are available when the control valve is combined with multi-spring diaphragm actuator or cylinder actuator. JPLS Control Valves are widely used in controlling small flows under high or low temperature or high pressure situation.
