Pressure Regulators


Founded in 1987 by gas industry scientists and engineers, CONCOA is today a recognised leader in the design and manufacture of gas control devices. The only company that routinely assembles specialty gas regulators in a cleanroom environment, CONCOA provides systems and equipment that perform precisely, under demanding conditions in diverse applications. Built for industries ranging from analytical, scientific, aerospace, environmental, and pharmaceutical, to electronic, medical, petrochemical, and metalworking - for those that require only the best.


CONCOA has proven Model of Pressure regulators for Laser cutting applications for use of Both lasing gas and assist gas supply e.g. Helium, CO2, Nitrogen and oxygen.

312 Series and 622 Series regulators are preferred choice of regulaors of Laser cutting industry in India.


1. Lateral Flow Passages

Instead of impinging directly on the diaphragm, the gas enters the low pressure chamber through a side orifice of the CAPSULE®. This smooth transition from high pressure to low pressure reduces the effects of gas surge on the diaphragm and minimizes regulator hum. In addition, the lateral flow passages induce a swirling effect which yields a completely swept internal cavity for complete purging.

2. Multiple Orifice Sizes

Each regulator has a specially designed CAPSULE® to optimize regulator characteristics over a broad range of applications. However, there are applications requiring higher or lower flows than the standard CAPSULE® can offer. By substituting a CAPSULE® with a larger or smaller orifice, CONCOA can tailor the regulator to meet a specific requirement.

3. PTFE Seat

The standard seat material is high density PTFE. PTFE is an inert material which will not react with or contaminate any high purity gas. In addition, PTFE retains its sealing properties over a wider temperature range than other seat materials. The inlet pressure rating of all CONCOA regulators with a PTFE seat is 3000 PSIG (210 BAR). With the optional PCTFE-seated CAPSULE®, the pressure rating increases to 4500 PSIG (310 BAR).

4. High Load Marginal Spring

The purpose of the marginal spring is to close the seat independently of gas pressures. The innovative CONCOA CAPSULE® utilizes a high force spring that assures a gas-tight seal under all conditions.

5. 10 Micron Filter

Particles trapped between the seat and orifice prevent proper seat closure, causing the regulator to fail. The CAPSULE® incorporates a 10 micron filter which completely surrounds the seat components to prevent the entrance of these damaging particles, virtually eliminating the cause of such seat failures. In addition, this filter is very fine, and its large surface area is resistant to clogging which allows unrestricted flow. The 10 micron filter is a key factor in the long life and reliable performance of all CONCOA regulators. The stainless steel 10 micron mesh CAPSULE® is patented CONCOA technology.
