Excess Flow Valves



We offer the 2000 series, which is our full line of excess flow valves, for all types of fluids and processes. Excess flow valves are in-line devices to limit the upstream or downstream flow when extreme under/over flow rates occur. We have manufactured the valves for all types of liquid and gaseous fluids. These fluids have included LP-Gas, Butane, Anhydrous Ammonia, Anhydrous Chlorine, air, water, Nitrogen, etc…. We have a wide variety of pressure classes, material options and flange designs. Please see our standard product line sheet for specifications. We will custom design and manufacture an excess flow valves to meet your exact specifications. All valves are tested to your specifications in our flow lab facility that is equipped with the state of the art data acquisition software.

2105 Series Excess Flow Valves are designed to easily insert between ANSI class flanges for use in liquid, gas or vapor service. These valves are lightweight, durable and offer a more generous flow rate than the 2100 model. Standard design on the 2105 Series valve has a weep hole to allow for pressure equalization once the valve closes. An optional external manual bypass system is also offered. This reduces the time it takes for pressure to equalize and the valve to reopen. 2106 series offers a design of a check valve and excess flow valve in one valve. The check valve will open at the desired cracking pressure and the excess flow side will shut off the flow above certain rate in the opposite direction.
