The GMI Diris check valve opens automatically under pressure from a fluid in a particular direction, and closes automatically to prevent fluid flow in the opposite direction.
The GMI safety valve automatically, and without the use of any energy other than that of the fluid concerned, discharges a quantity of fluid in order to prevent any overshoot of a predetermined safety pressure. It is designed to close and stop any further fluid flow after normal pressure operating conditions have been restored. The safety valve thus contributes to the safety of the installation by preventing any accidental pressure rise which would damage certain equipment such as: tanks, pipes, measuring instruments, etc.
The GMI Mathyl pinch valve is a valve that controls the fluid flow through the deformation of a flexible component: the sleeve. Sleeve deformation can take place directly and pneumatically or by mechanical compression.
All of our valves are made to the strictest quality standards and in compliance with the regulations in force (ISO 9001, DESP, EXAT, API, ASTM, ANSI, etc.). Our brand names are the guarantee of this commitment. Our insistence on quality and the reactivity of our sales department have won us the trust of the most demanding customers.
