Product Description
Common valve
The common rail valve assembly produced by Huahui Oil Pump and Nozzle Company adopts advanced electronically controlled fuel injection technology, which can achieve precise fuel injection control, significantly improve fuel economy and reduce fuel consumption. Its excellent fuel-saving characteristics can reduce driving costs and is suitable for various diesel engines, especially in heavy vehicles, construction machinery and agricultural machinery.
Valve assemblies are key components for equipment fluid control. It consists of valve body, valve core, etc., and is mostly made of corrosion-resistant stainless steel. The fitting accuracy between the valve seat and the valve core reaches ±0.01mm, which can accurately control the fluid flow, pressure and flow direction. It works stably and reliably, with a response time of less than 0.1 seconds, and is widely used in petroleum, chemical, machinery and other industries.
Overview
The Common Rail Valve Assembly is a crucial component in modern diesel fuel injection systems, responsible for regulating the high-pressure fuel flow between the fuel rail and the injectors. By precisely controlling the fuel pressure and timing, it ensures optimal injection performance, improved fuel efficiency, and reduced emissions. The valve assembly typically includes a control valve, sealing components, and precision-machined housing designed to withstand extreme pressure and temperature.
Built to meet the demands of high-speed, electronically controlled diesel engines, the common rail valve assembly is engineered using advanced materials and strict quality standards to deliver reliable, repeatable performance in both light-duty and heavy-duty applications.

FAQ
How many production lines in your factory?
5 production lines.
What is your MOQ?
100 pieces.
Can you design the equipment according to our size?
Yes.
What does a common rail valve assembly do?
It regulates the pressure and timing of fuel delivered from the common rail to the injectors, ensuring precise fuel injection for optimal engine performance.
What are signs of a failing common rail valve assembly?
Symptoms include hard starting, rough idling, reduced power, increased fuel consumption, and engine fault codes related to fuel pressure.
Can the common rail valve be cleaned or must it be replaced?
In most cases, due to its precision construction and internal sealing, the valve assembly should be replaced rather than cleaned if it is faulty.
Is this component compatible with all common rail systems?
No. Common rail valve assemblies are specific to engine models and fuel system designs. Always verify compatibility with your vehicle or equipment manufacturer.
