The Parker 90346 pneumatic valve, with its reliability, fast response, and low maintenance requirements, is an ideal choice for pneumatic systems in railway maintenance, helping to shorten repair time, reduce operating costs, and improve operational safety. The specific model selection should be further confirmed based on pressure, flow, and environmental conditions.
Compact Design for Confined Spaces
The Parker 90346 pneumatic control valve features a compact structural design and light weight. Supporting various installation types such as inline and through-hole mounting, it offers exceptional installation flexibility. This enables engineers to seamlessly integrate it into existing systems like brake control cabinets or door control modules, making subsequent retrofitting, maintenance, or replacement remarkably straightforward.
Wide Temperature Range Adaptability for Extreme Railway Environments
Featuring a specialized sealing design, the valve can withstand common railway environmental conditions such as high humidity, dust, temperature fluctuations, and vibration. With an operating temperature range of -10°C to +60°C, it maintains stable air pressure control performance on both frigid winter lines and scorching summer routes, without requiring additional temperature control devices. This makes it fully adaptable to all-climate railway operational demands.
High-Precision Control for Enhanced Train Ride Comfort
This pneumatic valve provides precise airflow control, ensuring the smooth operation of railway vehicle pneumatic actuators (such as doors and bogies). It reduces vibration and noise during operation, thereby enhancing the overall operational reliability of the train.
High-Speed Response for Train Operational Safety
It enables rapid air circuit switching, ensuring that railway signal and braking systems can respond instantaneously. This helps avoid train delays or safety hazards caused by control lag. In high-speed rail operations, this feature allows for precise control during emergency braking, reduces braking distance, and enhances passenger safety.
Rail Vehicle Braking System
Adapted for brake circuit pressure regulation in EMUs (Electric Multiple Units) and conventional trains, it matches braking response speeds under different operating conditions, contributing to the safety and stability of train braking.
Train Door Control System
Applied in high-speed and intercity train door opening/closing systems, it enables smooth and quiet pneumatic operation, ensuring safe and convenient passenger boarding and alighting, reducing door jamming failures, and enhancing the passenger travel experience.
Pneumatic Circuits for Railway Maintenance Equipment
Supports the pneumatic control of extension mechanisms in track inspection vehicles and maintenance equipment. With its wide temperature range and wear-resistant characteristics, it adapts to stable operation in complex outdoor maintenance environments.
Rail Vehicle Bogie Control:
Provides precise airflow regulation within the pneumatic control system of rail vehicle bogies, enhancing train running smoothness, reducing operational noise, improving passenger comfort, and extending the service life of key vehicle components.
How to Ensure Compatibility with Existing Railway Systems?
This product features seamless compatibility with most railway automation systems. Its straightforward installation process requires no major modifications to existing infrastructure, allowing for rapid integration into critical systems such as train braking and signal control, significantly reducing installation time.
What are the precautions for product installation and maintenance?
The valve supports multiple installation methods, offering great flexibility. During installation, ensure the connection ports are properly aligned and the appropriate tightening torque is applied to avoid valve body deformation due to mechanical stress. For maintenance, please refer to the specific guidelines in the product manual.
Does this pneumatic valve require special maintenance?
It is designed as a low-maintenance product, requiring only periodic inspection of seals and connections. For railway systems, we recommend a simple check every six months to ensure long-term stable operation, significantly reducing maintenance costs and system downtime.
