Product Introduction & Core Functions

Key Product Overview

Our spare parts cover critical categories: temperature sensors, proportional valves, pressure transmitters, torque meters, solenoid coils, industrial control units, and mechanical components—all designed to support the smooth operation of hydraulic and industrial equipment. Below is a detailed breakdown of core products, their functions, and how they solve common operational pain points:

21007714 Temperature Sensor (Type W-NR10242)

This sensor is exclusively designed for hydraulic gear shift and lubrication systems, solving the pain point of inaccurate temperature monitoring that leads to gear wear, lubricant degradation, and system failure. It features a high-sensitivity sensing element that detects temperature changes between -40°C and 150°C, with a response time of 0.3 seconds—faster than standard sensors by 0.1 seconds—to trigger timely cooling or shutdown signals. The sensor’s waterproof and dustproof design (IP67 rating) ensures reliable performance in dusty, high-moisture industrial settings, with a service life of 8,500 operating hours—2,000 hours longer than industry averages.

81655 Valve Proportional c/w Coil Type 157B4218 & 90707 Valve Proportional EEXD

These proportional valves address the challenge of unstable hydraulic pressure, which causes equipment jitter, inefficient operation, and component damage. The 81655 model integrates a high-performance coil (Type 157B4218) to deliver precise flow and pressure control, while the 90707 EEXD model is explosion-proof, making it ideal for hazardous areas. Both valves feature a corrosion-resistant stainless steel core, can withstand pressure up to 350 Bar, and have a leakage rate of less than 0.01 ml/min—ensuring minimal energy waste and consistent performance. They are compatible with most hydraulic systems, including those in Hydralift equipment.

56404 Transmitter Pressure EEXI 0-250 Bar w/10m Cable

Designed for Hydralift Hydraracker, this pressure transmitter solves the problem of inaccurate pressure readings in high-pressure hydraulic systems. It measures pressure ranges from 0 to 250 Bar, with an accuracy of ±0.25% FS, ensuring operators can monitor system pressure in real time and prevent overpressure failures. The 10m cable provides flexible installation in large equipment, and the EEXI certification ensures safe operation in explosive environments (ATEX Zone 1/2). The transmitter’s rugged design can withstand vibration up to 10g, making it suitable for heavy-duty industrial use, with a calibration interval of 24 months—reducing maintenance workload.

96219-11 Torque Meter (0-60K FTLB)

This torque meter is essential for monitoring load in industrial equipment, solving the pain point of overloading that leads to component fatigue and failure. It measures torque ranges from 0 to 60K FTLB, with a resolution of 10 FTLB, providing accurate real-time data to operators. The meter features a durable aluminum alloy housing, is resistant to oil and chemicals, and can operate in temperatures up to 80°C. It directly connects to most industrial control systems, including the P250000-9688-27 Industrial Control Unit, enabling seamless data integration and overload alerts.

Structure Features

All our spare parts share core structural advantages that enhance durability and performance: 1) High-quality materials—stainless steel, corrosion-resistant alloys, and industrial-grade plastics that withstand harsh environments; 2) Precision machining—CNC machining with a tolerance of ±0.005mm, ensuring perfect fit with original equipment; 3) Sealed design—IP65/IP67/IP68 ratings (depending on the product) to prevent dust, water, and oil ingress; 4) Modular design—easy to install and replace, reducing maintenance time by 30 minutes per replacement on average; 5) Compatibility—each part is engineered to match the exact specifications of original equipment, eliminating the risk of mismatched components.

Applicable Working Conditions

Our spare parts are designed to perform reliably in the most demanding industrial environments, including:

• Oilfield operations: High temperature (up to 120°C), high pressure (up to 400 Bar), dusty, and corrosive environments (compatible with Hydralift Top Drive, Hydraracker, and Gantry Crane Pipehandler).

• Hydraulic machinery: Continuous operation, high vibration (up to 15g), and frequent pressure changes (suitable for hydraulic gear shift and lubrication systems).

• Hazardous areas: Explosive gas environments (ATEX Zone 1/2, EEXD/EEXI certification) for parts like the 90707 Valve Proportional EEXD and 56404 Pressure Transmitter.

• Indoor/outdoor industrial facilities: Temperature ranges from -40°C to 150°C, humidity up to 95%, and exposure to oil, chemicals, and dust (applicable to all products in our collection).

Maintenance & Operation Tips

To maximize the service life of our spare parts and ensure optimal performance, our engineers recommend the following practical tips (based on 18 years of field experience):

• Temperature sensors (21007714): Clean the sensing probe every 6 months to remove oil and dust buildup; avoid direct contact with high-temperature surfaces (above 150°C) to prevent sensor damage.

• Proportional valves (81655, 90707): Inspect the coil and sealing rings every 12 months; replace sealing rings if leakage is detected (use only our matching seal kits, such as 64763 Seal Kit 125/70).

• Pressure transmitters (56404): Calibrate every 24 months using a professional calibration tool; protect the cable from sharp edges to avoid damage to the 10m cable.

• Torque meters (96219-11): Check the connection terminals every 3 months to ensure tight contact; avoid overloading beyond 60K FTLB, as this will reduce the meter’s service life by 50%.

• General tip: Store spare parts in a dry, cool environment (temperature 0-25°C, humidity ≤60%) to prevent rust and component degradation. Avoid storing near chemicals or sharp objects.

Engineer’s warning: Never use non-compatible spare parts as replacements—this can cause equipment failure, safety hazards, and void your equipment’s warranty. Our parts are 100% compatible with original equipment specifications, ensuring safe and reliable operation.
