Made from chemical- and stress-crack-resistant advanced polyethylene (PE) resin, Chem Proline Frank Series V86 back pressure regulators from Asahi/America are designed for water treatment and chemical process applications, including sodium hydroxide, sodium hypochlorite, caustic soda and low-concentration acids.

“We’re excited to expand on our Frank regulator product line that we have in other materials,” says Alex Gambino, engineering manager for Asahi/ America. “We set out to meet the operators’ requirement of having a direct anti-leak system, eliminating all threads in favor of a welded system.”

Made of the same material as its Chem Proline pipe and molded fittings, the polyethylene system eliminates joint leaks typically found in sodium hypochlorite and caustic PVC or CPVC lines.

Using heat, the polyethylene compound is fused into a homogenous joint that cures in seconds and leaves no weld seam.

The regulator is available in inline (1/2 through 2 inches) and angled configurations (1/2 through 1 inch) with either butt/IR or socket connections. Adjustable under working conditions, the regulator has an adjustable range of 7 to 135 psi, an outlet of 145 psi and low hysteresis of 1.5 to 8.7 psi.

“For an operator, it’s very easy to dial in what pressure you need for the system,” Gambino says. “Historically, you may have had to set the pressure at the factory, and they would give you a couple different spring rates for the valve. But if you’re able to adjust it from basically zero pressure to full operating pressure, which is 150 psi, it gives you a lot of flexibility if you need to make changes.” 800/343-3618;
