With the acquisition of AP Tech, SMC is now able to offer a wide range of products suitable for both low and high pressure applications and primarily applicable to the Ultra High Pure and Process Industries.

The core of AP Tech's product range includes Regulators and 3 Port Air Operated Valves. Their regulator range offers a choice of body materials from Brass, Stainless Steel 316L and Hastelloy for ultra pure applications. Allowable input pressures can be as high as 10,000psi and output pressures as low as less than 14 psi. Port Sizes range from 1/8" to 1” with a choice of threaded or welded connections.

Beyond the basic single stage option available to the customer, AP tech can supply a two stage regulator to counteract the supply pressure effect that can cause fluctuations in output pressure. The tied diaphragm type regulator can prevent leakage to the output if foreign matter becomes trapped between the seat and poppet, while the air operated specification allows a control pressure to vary the output pressure from a source supply as high as 3500psi (241 Bar)to between 0 and 150 psi.

AP Tech’s range of air and manually operated valves also operate at both vacuum and high pressures and are available in  Stainless steel and Hastelloy. Port sizes range from ¼” to ¾”. Manually Operated valves are available in ¼-turn, multi-turn and lever.

Both the manual and air operated types of valves are available with a lock out manual override function that preventions actuation in the case of maintenance.  

As well as high pressure and high purity regulators and valves, AP Tech also manufactures check valves suitable for high pressure applications, (1/4” connection size), vacuum generators and flow switches applicable to flow rates as high as 950l/min. In each case stainless steel 316L is the body material of choice.
