Membership on the B16 Standards Committee [1] and its Subordinate groups include a variety of representations from the field in various interest classifications. These interest classifications are; Manufacturer, Distributor, Material Manufacturer, Consumer/User, Designer/Constructor, Regulatory, Insurance/Inspection and General Interest.
This design results in significant increases in servo valve flow capability, stability, and force output. Similarly, three-stage servo valves may use an intermediate stage spool valve to position a larger third stage spool valve. Three-stage servo valves are limited to very high power applications, where significant flows are required.

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure , temperature , and liquid level.

Each of the pressure channels in the core has its own flow control valve so that the temperature distribution in the reactor core can be optimized. Each channel has a ball type flow meter. The nominal coolant flow through the reactor is 46,000–48,000 m 3 /h. The steam flow at full power is 5,440–5,600 t (6,000–6,170 short tons)/h. [16]
The sheet has a solid end and a flow-through end; sliding it from one position to the other opens or stops the flow. Also called sliding blind valve; Outflow valve: regulates flow and pressure, part of cabin pressurization; Pilot valve: regulates flow or pressure to other valves; Petcock, a small shut-off valve
