American Thermowell multi-stage restriction orifice is the perfect solution when the required pressure or flow drop is not possible with a single plate.
Made up of multiple orifice plates, each reducing pressure with calculated reduction steps to achieve the required drop in the pressure and/or flow. A restriction orifice run can also greatly reduce noise and vibrations, as well as flashing or cavitation in the line. Our multi-stage restriction orifice assembly can replace a valve for a simple, maintenance free and economical solution.
Reduce the pressure drop, not achievable with a single plate.
Prevents flashing, cavitation and other critical flow problems.
Single hole multistage design along with multi-hole, multi-stage designs available.
Line sizes: 1/2” – 24”. Flange Rating: 150# – 2500#
Built to optimize the pressure drop across each stage
Suitable for both high flow/pressure liquids and gas
Designed based on ASME.MFC.3M industry standards
Low maintenance costs
