Series AP is an ultra high purity (UHP) regulator for gas delivery in semiconductor and other clean industries.  The series is available in low to high flow capacities, with some models offering a tied-diaphragm design. Available options include Hastelloy® internals for corrosion resistance, a tube stub weld fitting connection type, and various surface finishes.

Series AZ is an ultra high purity (UHP) regulator for gas delivery in semiconductor and other clean industries. The series is available in low to high flow capacities, with some models offering a tied-diaphragm design. Available options include Hastelloy® internals for corrosion resistance, and a tube stub weld fitting connection.

Series SL is an ultra high purity (UHP) regulator for gas delivery in semiconductor and other clean industries. The series has a springless design (no poppet spring in the wetted area), and is available in low to intermediate flow capacities. Available options include Hastelloy® internals for corrosion resistance, a tube weld fitting connection type, and various surface finishes.

Series AK regulator was designed for general use in a wide variety of applications. The series is available in single or two stage models, with low to high flow capacities.  Some AK regulator models offer a tied-diaphragm design. Available options include Hastelloy® internals for corrosion resistance, panel installation, and a variety of pressure gauges in psig/bar or MPa units.

The KT10 and KT12 series are regulators used in gas delivery systems to reduce the pressure to a lower delivery (outlet) pressure.  These regulators are available with a self-relieving (venting) option, which vents process gas through the regulator cap directly into the atmosphere, or a non-relieving (non-venting) option, which must be used in combination with hazardous gases.
