Pentair Valve Alternative

Pentair Valves & Controls (now Emerson)

Pentair Valves & Controls (formerly Tyco Flow Control) was a major manufacturer of safety relief valves (Anderson Greenwood, Crosby), butterfly valves (Keystone), and check valves before the brand was acquired by Emerson in 2017. The Keystone butterfly valve range and Crosby/Anderson Greenwood safety valve product lines are widely specified in refineries, chemical plants, and offshore platforms. Vajra Industrial Solutions supplies equivalent API 526 safety relief valves and API 609 butterfly valves that meet or exceed the original Pentair/Tyco specification.

Legal DisclaimerPentair, Anderson Greenwood, Crosby, and Keystone are registered trademarks. Vajra Industrial Solutions is not affiliated with Pentair or Emerson. All safety valve replacements must be engineered and approved by a qualified pressure relief engineer (PRE) to ensure equivalent relieving capacity and set pressure accuracy.

Why Consider Pentair Alternatives?

Post-Emerson acquisition pricing is higher — independent suppliers offer competitive alternatives
Long lead times from Emerson/Pentair on non-standard orifice sizes
Replacement valves for existing Keystone / Anderson Greenwood specifications
Budget-constrained turnaround projects needing equivalent quality at lower cost

Pentair → Vajra Equivalence Reference

Indicative equivalences for common Pentair valve series. Dimensional and specification compatibility must be verified by the project engineer before substitution.
