Neoprene Valve resists waxes, fats, oils, greases, petroleum products, and most refrigerants.
Nordel Valve is an ethylene-propylene based synthetic rubber for hot and cold water, low steam, detergents, phosphate esters, ketone, alcohols, and glycols.
This information is a general guide and product should be tested for applicability under actual conditions.
How to Operate:
These plugs are permanently installed in the line at recommended test points. The cap protects the valve and provides an additional seal. After the cap has been removed, either a test thermometer or a gauge adapter with the proper pressure gauge can be inserted through the two, self-closing valves in the plug. Readings are made, adjustments or test can be accomplished and when the probes are withdrawn, the two valves close. The protective cap is then reinstalled. Tests should be made as quickly as possible since the valve reseal time is dependent upon time of insertion, time, and pressure. Slower valve reseal time can be expected at lower temperature and lower pressures.
Features:
- Available in 1/4" and 1/2" NPT sizes
- Available in long length
- Brass body material for non-corrosive service
- Pressure limits to 1000 psi depending on application
- Neoprene core (red cap) for temperature range of 0-200°F, for use with natural gas and petroleum products
- Nordel core (blue cap) for temperature range of 0-275°F, for use with hot and chilled water systems
- Valve core is self-sealing with pressure cup for superior sealing protection
- Tested by an independent lab indicates no leaks at high or low pressure
