Good Selling 2 Way Flow Control Valve​ Company

Product Overview

- The Good Selling 2-Way Flow Control Valve, produced by CHONGQING CHANGJIA INTERNATIONAL TRADING CO., LTD, is a precision hydraulic valve family (types DV and DRV) designed for accurate oil flow metering and optional shut-off. It is engineered by experienced designers using modern concepts and offered with professional after-sales support.

Product Features

- Two main variants: DV (throttle/isolating — sets flow and can shut off) and DRV (throttle/check — sets flow in one direction, permits free return flow the other way).

- Construction: housing with adjustment knob, spindle and throttle pin, colour scale for repeat settings, and locking device to fix the set flow.

- Connection/mounting: threaded connection and subplate mounting. Installation position optional.

- Materials: steel, brass, or stainless steel.

- Key specs: max operating pressure up to 35 MPa (steel/stainless), up to 15 MPa (brass); cracking pressure typically 0.05 MPa (other values on request); compatible fluids: mineral oil or phosphate ester; temperature range -30 to +80 °C; viscosity 10–800 mm²/s.

Product Value

- Provides precise, repeatable flow control and reliable shut-off capabilities, improving hydraulic system performance and process control.

- The built-in check function (DRV) simplifies circuit design by allowing controlled flow in one direction and free return in the other.

- Robust material options and wide pressure/temperature/viscosity ranges make it suitable for demanding industrial applications, enhancing uptime and reducing maintenance.

Product Advantages

- Superior build quality and design compared with competing brands, backed by ChangJia’s long-term experience and professional after-sales service.

- Flexible installation (threaded or subplate) and selectable materials for compatibility with different systems and environments.

- User-friendly adjustment with colour-scale feedback and locking device for secure, repeatable settings.

- High maximum pressure ratings and the option for customized cracking pressures increase applicability across heavy-duty hydraulic systems.

Application Scenarios

- Industrial hydraulic systems (presses, machine tools, manufacturing lines) requiring accurate flow metering or isolation.

- Mobile and construction machinery hydraulics where controlled actuation and reliable return flow are needed.

- Agricultural equipment, marine hydraulics, and power units using mineral oil or phosphate ester fluids across -30 to +80 °C.

- System retrofits and new designs that demand robust, adjustable flow control with repeatable settings and secure locking.
