Sun Hydraulics Cartridge Valve 20gpm CSAD-XXN 100% New Original

SUN HYDRAULICS CSAD-XXN ‌Long Life High Reliability 100% New Original

Product Description:

1. Advantages and Features

High reliability structural design

The floating valve tail design reduces the sensitivity to installation torque and avoids the internal components from getting stuck. It also allows higher installation torque (such as NFED-HHV model) to ensure stability and reduce the risk of oil leakage.

The thread shoulder flat design bears the load, optimizes the flow capacity and disperses the thread stress, reducing the impact of eccentricity on the oil circuit (such as CBCGLJN model).

Efficient sealing and space optimization

The socket is equipped with precision O-ring guide angle and sealing area, with a surface finish of more than 63Ra, which effectively prevents oil leakage and supports hydraulic systems with large flow and low pressure loss.

The modular design reduces the need for pipeline connection and saves installation space. The valve core can be replaced without disassembling the pipe joint during maintenance, reducing downtime.

‌Widely applied and flexible adaptation‌

Covering scenes such as engineering machinery, ships, and mining, especially suitable for harsh environments (such as corrosion-resistant stainless steel materials support phosphate media, and EPDM seals withstand extreme temperatures of -60℃~120℃);
Provide multiple models (such as NFED-HHV, CBCGLJN, etc.), support different flow requirements (flexibly expanded through the oil circuit board).

‌Long life and low maintenance cost‌

The internal components are heat-treated, with excellent wear resistance and fatigue resistance (such as hardened alloy gears), and the service life is significantly extended;
No additional grease is required for lubrication, and the maintenance cycle is long. Only the seal status needs to be checked regularly (such as cleaning the filter element every 500 hours).

2. ‌Precautions for use‌

‌Installation specifications‌

Before installation, ensure that there are no scratches or missing on the threaded area of ​​the jack, and keep the O-ring guide angle smooth to avoid sealing failure;
The control cover must be aligned with the oil port or positioning pin, and the fixing screws must be made of high-strength material (grade 10.9 or grade 12.9), and tightened in stages to prevent spring overload.

‌Media and Environmental Limitations‌

Models with EPDM seals are prohibited from contacting petroleum-based hydraulic oil or grease (only compatible with phosphate ester media), otherwise the seal will age faster;
When the operating temperature exceeds the range of -60℃~120℃, special sealing materials (such as fluororubber) must be used to avoid high temperature causing the seal to harden or crack at low temperature.

‌Operation and Maintenance Requirements‌

The oil cleanliness must meet the NAS 1638 Level 6 standard, and the filter element impurities must be cleaned regularly to prevent the valve core from getting stuck or wearing;
Before long-term shutdown, the system residual oil must be drained and anti-rust oil must be injected to protect the internal components.

‌Adaptation and Compatibility‌

When replacing seals or valve cores, original accessories (such as Sun's special EPDM seals) must be used to ensure seal compatibility and control accuracy;
When designing integrated valve blocks, avoid mixing with standard valve blocks of incompatible materials (such as EPDM seals cannot be integrated into valve blocks with nitrile rubber seals).

‌Key Tips‌:

Multi-valve linkage requires PLC calibration of synchronization parameters to prevent action delays from causing system conflicts;
The first commissioning after installation requires gradual pressurization to avoid instantaneous high-pressure shocks that damage the sealing structure.
