 The ACL P172 Series is a line of 2-way proportional pneumatically operated angle seat valves with ISO G connections sizes from 1/2” to 2”G (BSP), NPT threads are available on request.  Depending on size the P172 series offers a maximum operating pressure differential (MOPD) of up to 16 bar.

The main advantage of the angle seat configuration is that compared with other valve types it gives a high flow rate with low pressure loss.  Other benefits include: elimination of water hammer and also resistance to back flow.

The body is made from AISI 316 stainless steel making the P172 suitable for use with aggressive media and food products.

The actuator body is manufactured in robust glass-filled nylon and incorporates an optical position indicator to allow correct operation of the valve to be visually confirmed.

To simplify installation the P172 can be mounted in any orientation and the pneumatic actuator can be rotated to give the most convenient orientation for making pneumatic signal connections which are 1/4”G female thread.  The pilot signals can be provided with either dry or lubricated air or suitable gases and neutral fluids.  Gaskets within the actuator are produced in NBR.

To minimise maintenance the P172 features self-adjusting packing glands using PTFE and FKM seals for long life and maximum chemical compatibility.

The P172 series uses a PTFE main seal and has been designed for use in the applications that include: automation, heating, water, hot water, steam (<180°C), aggressive media and food products.  These valves can handle media with a temperature range between -10°C and +180ºC in an ambient temperature of -10°C to +80ºC.

ACL srl have 30 years experience of manufacturing high quality valves at their factory near Milan, Italy, all products are CE marked and (where appropriate) comply with the Pressure equipment directive 97/23/CE. Beta Valve Systems have been ACL’s UK distributor and stockist since 1992.
