Seal for hydraulic aerospace systems

Greene Tweed | tweed.com

New L-Cap seal for hydraulic systems in aerospace applications is made with proprietary Avalon PTFE, Arlon PEEK, and elastomer materials. It exceeds industry standards for performance and durability, ensuring long service life, minimal fluid leakage, and excellent performance across a broad temperature range.

Used in critical flight actuation systems, the L-Cap seal provides superior fluid sealing in hydraulic cylinders under high pressures. The proprietary Avalon PTFE, Arlon PEEK, and elastomer materials ensure high durability and minimal wear over the lifetime of an aircraft. These proprietary materials exceed the low-temperature performance requirements set forth by aviation industry standards without sacrificing high-temperature performance.

The L-Cap seal also delivers unmatched leak prevention, exceeding customer requirements for minimizing hydraulic fluid leakage. L-Cap seals are also easier to install than other aviation rod seals, reducing actuation system failures upon initial startup.

High-pressure proportional pressure controls

Clippard | clippard.com

The Cordis HP500 pressure controls use the EV line of electronic valves allowing for steady, repeatable downstream pressure under static conditions. The result is a precise linear pressure control within a closed-loop system. The Cordis uses a microcontroller, integrated pressure sensor, and two Clippard EV electronic valves. The inlet valve is connected to the moderately regulated supply pressure, and the exhaust valve is connected to a port that vents excess pressure to the atmosphere. Once a command is increased, the inlet valve opens up to allow supply pressure to pass over the sensor element providing an active feedback for the micro-controller to satisfy the set point in the process. If at any point, the sensor detects a value higher than the set point, the exhaust valve will modulate open to vent off the excess pressure to maintain a stable and accurate control pressure in the process. The Cordis HP500 pressure regulator is adaptable to a variety of sensors that can close the loop around pressure. It offers:

• Smooth linear control

• Pressure range of 0 to 500 psig

• Integrated internal or external sensor feedback

• Customizable pressure ranges and mounting options

Screw-in, cartridge-style hand pump

Doering | doering.com

The DCHP102 screw-in, cartridge-style hand pump with integrated dual check valves is suitable for hydraulic backup, hydrostatic testing, heavy-equipment parking brakes, and safety applications — this hand pump displaces hydraulic fluids. The seat is made from hardened steel for long operating life. Doering’s standard plating, used on the DCHP102, has superior corrosion resistance. The piston is treated and hardened for improved wear and corrosion, heat, and friction resistance.

Doering’s DCHP102 hand pumps are available for operating pressures of 2,100 psi (145 bar) or 3,000 psi (207 bar). Their operating temperature ranges are –40 to 212°F (–40° to 100°C). The lever socket rotates 360°, and handle lengths are 9, 16, 20, and 24-in.

Fluid condition monitoring kits

Schroeder Industries | schroederindustries.com

Schroeder Industries introduces the all-new plug-and-play Condition Monitoring Starter Kits for real-time fluid condition.

Contaminated hydraulic fluid is the leading cause of system downtime. Full line of top-tier sensors catch less-than-ideal hydraulic fluid before it enters the system. The Condition Monitoring Starter Kits (#1-4) are plug-and-play packages that provide the technology, necessary cables, hoses, and wires all in a single purchase order — everything operations managers need to start monitoring (and saving) their hydraulic equipment like a pro. The Condition Monitoring Starter Kits come in four unique sets: Local Data Display (#1), IoT (#2), HY-TRAX IoT (#3), and CSM-Economy (#4).

Pneumatic valve with embedded wireless connectivity

Emerson | Emerson.com

Emerson has introduced a wireless automatic recovery module (ARM) for its Aventics G3 electronic fieldbus platform that makes it easy for technicians to perform pneumatic valve system commissioning and diagnostics from a mobile phone, tablet or laptop computer.

The ARM module and Aventics G3 fieldbus platform are suitable for pneumatic valve system applications in the automotive, food and beverage, tire, packaging, and metalworking industries.

The module provides easy access to the Aventics G3 fieldbus platform’s diagnostic and commissioning capabilities via an internal Wi-Fi access point and mobile website . It offers visual benefits of a hard-wired HMI. The wireless ARM module generates error notification for alarms, voltage levels, short circuits, module errors, open load errors, and distribution errors to reduce system downtime.

The device has a small footprint that connects easily to the Aventics G3 fieldbus platform in the space of a jumper clip. It has three power settings for low, medium, or high-distance signals to ensure safe and secure access to data — regardless of where the valve system is mounted.

Electronic proportional flow control valve

Spartan Scientific | spartanscientific.com

STEP 12 self-contained, media-separated electronic proportional flow control valve brings a new perspective to controlling liquids and gasses. With more than 1,500 different positions (or steps), it precisely regulates flow output and requires minimal power to maintain a desired position, maximizing energy savings.

The STEP 12 is self-contained with control circuitry (including an innovative M12 connector) for both the motor and valve embedded into the unit. This eliminates needing to purchase a separate control device, which can compromise performance. In addition, control can be tailored to increase resolution, enhancing reliable and repeatable flows. Additionally, the valve is designed for full flow under maximum pressure conditions with a ½-in. NPT version capable of accommodating 30 gpm of water with a maximum pressure of 150 psi.
