Amflow® AM8C Series Flow Control Valve

Amflow® Flow Control Valves represent the latest technology in patented Dual Piston technology developed by A & H Enterprises.  Our ATEX-certified chemical injection valves have the highest turndown ratio in their class, operating over a far wider range of flow rates than traditional valves, with repeatability and accuracy within ± 3% full range.  All of Amflow’s® Flow Control Valves can be configured for an automated or manual flow rate adjustment.

Flow control is set by the internal pressure of the valve and not the overall system pressure, allowing for minimal operating torque for flow adjustment and easy adaptation to automation.

Chemical Injection System Integration

Multiple flow control valves can be installed in a single pump or supply header chemical injection system, limited only by the output of the supply source.  Unlike chemical injection pumps, our chemical injection valves require little to no maintenance.  A purge port allows the user to direct a high flow stream of chemicals across the fixed orifice in order to flush any chemical residue or debris that might accumulate over time. This feature reduces the necessity of opening the valve and cleaning jets manually and significantly lowers maintenance and replacement costs.

Flow Valve Construction

Amflow® Flow Control Valves are constructed using high-quality 316L Stainless Steel, features static o-rings, and high-pressure seals for leak-free operation.

AM8C Series

For chemical injection applications requiring a range of flow rates from 1.00 LPH up to 600 LPH, the ATEX-certified AM8C Flow Control Valve features our patented Dual Piston technology.  The AM8C is pressure independent for reliable metering across a wide range of chemicals.  This self-regulated design provides a standard turndown ratio of up to 50:1, with reputability and accuracy within  ± 3% full range.

The AM8C is able to pass 1.00 mm particles, making it suitable for chemical injection applications with some debris in the process line.  The AM8C may be combined with any of Amflow’s Electronic Actuators.
