H6800 - High Perform. Ball Valves

Product catalog summary
Overview: The H-6800 and H-6800 CNG Series are high-performance ball valves designed for general service and instrumentation panels. They provide tight shutoff, long service life, and low operating torque. The H-6800 Series is rated up to 6000 psig, while the H-6800 CNG Series is rated up to 3770 psig.
Material of Construction: These valves are made from materials such as Stainless Steel (St.St.316), Brass, and PTFE/PEEK, ensuring durability and performance under high pressure and temperature conditions.
Features: The H-6800 Series offers 2-way and 3-way patterns, with options for stainless steel and brass construction. It supports various end connection types and sizes, features adjustable packing, panel mounting, and replaceable handles, and is certified for ISO 15848-1:2006(E).
Pressure and Temperature Ratings: The valves can handle a maximum allowed working pressure (MAWP) of 6000 psi and a maximum allowed working temperature (MAWT) of 500ºF. Different seat materials like Modified PTFE, PCTFE, and PEEK are used based on application requirements.
Testing and Certification: The design has been tested for burst and proof, with standard testing including nitrogen testing at 80 & 1000 psig. Special cleaning and packaging options are available.
Applications: The H-6800 Series is suitable for general service, while the H-6800 CNG Series is specifically designed for CNG/NGV applications with ECE R110-type approval.
Dimensions: Detailed dimensions for various configurations and end connections are provided to ensure compatibility with different installation requirements.
Material of Construction: The document lists materials used for various parts of the H-6800 series valves, including PTFE, Fluorocarbon FKM, Silver plated Stainless Steel 316, ASTM A-479, ASTM A-276, PEEK, and others.
Features: The H-6800 series valves are ECE R110, Class 0 approved for CNG/NGV applications, with a MAWP of 3770 psig (260 barg) and a temperature range of -40°C to 120°C. They feature variable LET-LOK® end connection sizes and are constructed from stainless steel with spring-loaded seats, approved for 20,000 cycles.
General Information: Four standard actuator sizes are available, improving operational speed for better valve control. Actuators comply with industry standards and are available factory assembled or separately. The temperature range for actuators is -32°C to 90°C, with optional high and low-temperature variants.
Ordering Information: Details on ordering the H-6800 series valves and actuators are provided, including end connection types, body materials, handle options, and seat materials. Information on ordering spare kits for seals and handles is also included.
Warnings and Recommendations: The document emphasizes the responsibility of the system designer and user to select suitable products for their applications, considering material compatibility and product ratings to ensure safe installation and operation.

PACKING ADJUSTMENT The H-6800 design has been tested for Burst and Proof. Standard testing for each H-6800 valve includes testing with nitrogen at 80 &1000 psig. Each valve is tested for leakage through the shell, packing and ball seats. The maximum allowable leakage across the ball seats is 0.1 std cc/min. Due to the varied service applications of the valve, packing adjustment may be occasionally necessary. Packing is factory adjusted to 1000 psig service. Initial adjustment is recommended after installation and prior to start-up. Please find more information in the installation instruction...
