Tyco (Vanessa / Keystone) Valve Alternative
Tyco Flow Control (now Emerson Automation Solutions)
Tyco Flow Control (previously Tyco International) was a global valve brand that owned Vanessa triple-offset butterfly valves, Keystone resilient and high-performance butterfly valves, Anderson Greenwood / Crosby safety relief valves, and Biffi actuators — all subsequently consolidated under Emerson Automation Solutions. Vanessa Series 30,000 triple-offset butterfly valves are widely specified in refinery and petrochemical critical services for their metal-seated, fire-safe, zero-leakage performance. Vajra Industrial Solutions supplies equivalent triple-offset butterfly valves meeting API 609 Category B, ASME B16.34, and fire-safe requirements.
