Ball seat design, hard facing and soft seat options

Ball seat design

Maintains tight contact between ball/seat regardless of valve installation orientation.
Low coefficient of friction
Excellent sliding and running properties
Optimal selection of flexibility and stiffness of both ball and seat rings
Thermoplastic seat materials Graphite, Devlon, TFM, PTFE, RPTFE, PEEK, POM, PCTFE, Nylon

Hard facing and soft seat options

To prevent wear and tear controlling physical and chemical characteristics, Red Point uses several qualified surface treatment techniques to increase the service lifetime of valves and its components. Depending on the material in question, pressure/temperature and service conditions a few techniques can be used. These surface treatments, in combination with a high class design, entered to your specific process conditions, will result in a high quality valve, which guarantees a long cycle life.

HVOF like Chromium- and Tungsten Carbide.
Chromium- and Titanium Oxide, Nitriding

Thermoplastic seat materials Graphite, Devlon, TFM, PTFE, RPTFE, PEEK, POM, PCTFE, Nylon

Applications for Top Entry Construction Ball Valves

Red Point’s top entry soft seated ball valves can be deployed for a wide variety of applications in the oil & gas, (petro) chemical, mining and power industries when high quality and highly reliable valves are required. A few example applications include:

• High-cycle and switching services
• Emergency shutdown valves (ESDV)
• High-integrity pressure protection system (HIPPS)
• High-pressure oxygen, nitrogen or hydrogen
• Polyethylene or polypropylene
• Oil & Gas sevices
• Hydrogen
• Food/Pharma
• Toxic/Lethal Service
• Autoclave sevices
• Coal conversion and gasification
• Separator, filter and drying systems
• Compressor stations
