* Create part number
by adding orifice size in inches. Example: CTES25030 A
defines a 1/4" - 28" Cv Restrictor with 0.02" orifice
Notes:
- Materials:
All Cv Restrictor bodies are 100% 303 stainless steel per ASTM A582,
with the exception
of pipe thread sizes made from brass. Expander pins are 17-4 stainless steel.
- Orifice Tolerance:
Standard tolerance is +/-.001".
- Cv Restrictors can be installed in the fitting you require.
- Contact the factory for special materials, flow testing, or other special requirements.
