For Flowserve, a Low Flow valve is a valve with a range of Cv values between 0.01 to 4.7. Flowserve also manufactures Micro Flow valves designed to offer lower Cv than 0.01 and down to 0.0000012.
In the Flowserve control valve portfolio, a wide range of valves is designed to offer both ranges.
These products are widely used for applications in laboratories and industrial research departments, as well as industrial processes requiring high degrees of control accuracy.

Technical Data
- Series 080000 low flow laboratory valves are designed for precision controlling. The body is manufactured from bar stock stainless steel and is easily adapted to meet application requirements. Together with the series 1 actuator, it forms an extremely compact control valve.
- Series 385000 is the 1/2″ version of Flowserve’s low flow valve product offering. End Connection sizes of up to 1″ or DN 25 are possible. The cast body design allows for pressure ranges of up to CL 600 / PN 160 with a max. Cv of 4.7.
- Series 020000 are split body style valves manufactured from forged material. This engineering design easily adapts to meet application requirements and makes the valves easy to clean and maintain. Configurations as globe, angle, or 3-way valve design for easy maintenance. Standard 1/2″ Body size with end connection sizes up to 1″ (DN25). Pressure classes up to CL2500 or PN400. The seat is clamped in between the upper and lower body, which allows changing the trim without any special tools.
- Series 030000 is a “General Service” Low Flow Valve. The standard body material of this 1/2″ valve is cast stainless steel. Various end connection types, such as screwed ends or flanges, as well as special end connections for laboratories or food and beverage applications, make the Series 030000 our choice for all standard applications where the Cv value is below or equal to 2.9. With APV flanges PN10, the series 030000 becomes a light-duty 1/2″ valve for the food and beverage industry for carbonizing applications.
- Series 185000 are 1/2″ valves designed for precision controlling. The body, made of carbon steel or stainless steel forged, or for any other application out of barstock material, can easily adapt to meet application requirements. Together with the series 1 actuator, it forms a compact control valve (285000).
