LMD series

Product catalog summary
Introduction
The document introduces the LMD Series, a new lineup of air-operated valves designed for handling chemical liquids. These valves are highlighted for their high quality, performance, and user-friendly design.

Specifications
The LMD Series comprises five models with orifice sizes from ø6.3 to ø20. They accommodate various connection diameters and are compatible with the AMD Series for installation. Suitable for chemical liquids, pure water, air, and N2 gas, they operate within a fluid temperature range of 5 to 60°C and can withstand pressures up to 0.8 MPa.

Design and Features
The valves include a two-point fixed bracket for compact installation and a new flared tube fitting. Options available are indicators, flow adjustment, and fluorine resin coating for metal parts. The operation pressure range varies with actuation type (NC, NO, or double acting).

Installation and Operation
Valves can be installed in any orientation and are compatible with FIT-ONE fittings. The operation pressure connection port is Rc1/8, and they are designed for a frequency of 30 times/min or less.

Safety and Compliance
Emphasizing the importance of adhering to specifications and safety standards like ISO 4414 and JIS B 8370, the document outlines precautions for handling, installation, and maintenance to prevent accidents.

Warranty and Export Control
The warranty period is 18 months from the first delivery, detailing the scope and exclusions. Export approval under the Foreign Exchange and Foreign Trade Control Law is necessary for certain products and technologies.

Conclusion
The LMD Series valves are designed for industrial use, offering flexibility, safety, and high performance for chemical liquid handling. Proper selection, installation, and maintenance are crucial for optimal operation.
Product Specifications and Compatibility
Emphasizes confirming product specifications compatibility with the system before use. A checklist ensures materials suit the working fluid and environment. Consultation with CKD is advised for unlisted or new fluids.

Temperature and Pressure Guidelines
Products should be used within specified fluid temperature and working pressure ranges. For hazardous fluids, valves should be placed in inaccessible locations to prevent injury.

Design Considerations
High purity chemical gas/liquid control systems require careful design. Safety precautions include securing maintenance space and installing relief valves to prevent abnormal pressure.

Installation and Adjustment
Proper installation and piping are crucial to avoid product and system issues. Systems should be operated by knowledgeable personnel. Piping should be flushed before valve installation, and filters should be used to prevent foreign matter from affecting valve function.

Maintenance and Inspection
Regular inspections are necessary for optimal valve operation, including checking for leaks, discoloration, deformation, and corrosion. Maintenance should be conducted with power off and fluids or pressure released.

Safety and Performance Precautions
Periodic inspections are recommended for systems using chemical liquids with high permeability. Coated metal options are advised for corrosive fluids to prevent corrosion and leakage.

Compatibility Checklist
The checklist provides compatibility information for various fluids, including pure water, acids, and gases. Users are responsible for confirming compatibility, especially for mixtures and unlisted substances.
