EnviroValve is a company specialised in pressure relief devices that has gained international visibility thanks to its ACCU-SHEAR® technology, developed to provide precise relief, high sealing integrity and rapid reset. Its offering is clearly oriented towards plants where trip reliability and rapid service recovery have a direct impact on safety, emissions and availability.
ACCU-SHEAR® technology employs a butterfly-type design to generate rapid and efficient relief, combined with a pre-loaded pin system that helps resist pressure variations during operation without premature fatigue of the trip element.
This architecture allows operation with good opening accuracy, very tight shutoff and an extremely rapid manual reset via simple pin replacement, notably reducing the time the line is out of service.
Its application is concentrated in petrochemical, refining, chemical, pulp and paper and other process industries requiring reliable relief with low unavailability after the event.
EnviroValve provides a well-focused response when the objective is to combine relief precision, good sealing integrity and rapid reset.
