YQ20012 piston flow control valve

YQ20012活塞式流量控制阀 is a key equipment that achieves stable flow after the valve through fluid pressure self-control. Its core working principle is based on the pressure difference signal transmitted by the pitot tube: when there is a pressure difference between the two ends of the valve body, the pressure difference drives the main valve piston to move, and at the same time, the flow limiting pilot valve and needle valve cooperate to control the position of the valve core, dynamically adjusting the cross-sectional area of the flow channel to maintain the set flow rate.

Technical features and functions
Dual parameter control capability
YQ20012 piston flow control valve
Synchronize the flow and pressure after stabilizing the valve, and install a filter screen to prevent impurities from clogging the valve core.
Adopting a non orifice plate throttling design, the flow rate and pressure values are directly set by adjusting the bolts through the pilot valve, with precise operation and no additional energy loss.
Anti interference structure design
The Y-shaped wide body valve chamber reduces flow resistance, combined with the design of the piston lower chamber orifice, which can buffer the impact of valve closure and significantly reduce the risk of cavitation and noise.
Modular components (such as E-type/S-type outlet regulating components) are adapted to different working conditions, such as eliminating cavitation damage by bending the DC channel in high voltage differential scenarios.
Application scenarios
Mainly suitable for scenarios in water supply networks that require precise control of flow and pressure, such as:
Municipal water supply and drainage system: stabilize the output flow of water pumps to prevent water hammer impact;
Industrial circulating water control: regulating fluid parameters under high pressure differential environment (such as controlling flow at the inlet of the reservoir);
Fire/air conditioning piping: relying on the self driving characteristics of the medium, it can operate for a long time without external energy.
