1.) Select a size , 2.) Select a spring range, 3.) Since the Body contains the pressure, select the proper material that is suitable for the fluid or gas used. 4.) The Spring chamber, spring hardware and the adjusting spring are isolated (non-wetted) from the fluid media and should be selected based on the external environment the valve is exposed to. The carbon steel spring chamber, when selected, is painted on the exterior and interior to withstand normal atmospheric corrosion. Unless specially ordered, the adjusting spring is always a high strength chrome silicon spring steel which is completely protected inside the enclosed spring chamber. After the customized selection is made, click to continue, and instructions will be provided to either print or save the selection or to proceed with ordering the item on line. Printing the selection will not commit one to ordering the items selected. Should you have any questions on the product capability or product options, or are having difficulty in making the pricing selections or ordering, please contact us by e-mail or phone between 9AM-5PM Eastern time, Monday-Friday.

HWRS 2023 was a success! Over 320 attendees had a fantastic time sharing ideas, catching up with old and new friends and playing a giant rivers and fish ladders hydrologic games! A big thanks to everyone involved, including the local organizing committee, NCWE, keynote speakers, session chairs, paper reviewers and panel members. Without your hard work and dedication, this event wouldn't have been possible! To all those who didnt make it you missed a great conference. Looking forward to seeing you all next year in Melbourne in late November! #HWRS James Ball Behzad Jamali @brendan berghout Mark Babister Chris Thomas Ian Rowbottom M. van der Sterren Sabina Lohani Stefan Felder Rhys Thomson Francis Chiew @allan goyen Geoffrey O'Loughlin @richard kingsford Duncan McLuckie Rebecca Nelson Holger Maier Maree Abood Katherine Daniell Leanne Pearce William Glamore Carlos Gonzalez Christopher Russell Martin Giles Warren Martin Rory Nathan Acacia Pepler Anna Ukkola Ben Henley Leanne Wilkinson Simon Koger Conrad Wasko Jamie Burrage Michael Leonard

Waterpressureregulator

This valve operates with a compression spring acting on the main valve which is used to adjust the outlet pressure with an adjusting screw. The reduced outlet pressure is very easily adjusted in the field. To increase outlet pressure, simply loosen adjusting screw lock nut (2) to increase spring compression by turning the adjusting screw (1) inward. Similarly, to get a lowering in outlet pressure requires a reduction in spring compression by turning the screw outward. A pressure gauge is required on the outlet side of the regulator somewhere in the downstream piping close to the valve, to monitor the result while making the adjustment. The valve will operate in a vertical orientation as illustrated, horizontal, or any other orientation.

Designed for clean, filtered or strained, non-abrasive liquid service: oils, lubricants, greases, solvents, and most non-fluorinated chemicals compatible with Teflon PTFE seals. Valve is piston-operated, metal-seated without any elastomers. Do not use for extended shutoff service or for extremely low flows (less than  5% of maximum capacity, approximately). Values below the low limit of the spring ranges shown below can be achieved if the flow rates are substantially higher than the minimum 5% of maximum rated capacity. To be on the safe side, a relief or bypass valve should always be installed on the outlet side of the regulator (not included with valve). For outlet pressures below the ranges stated below, request model PRH09-FLG double piston model, that is specifically designed to handle the lower outlet pressures that the PRH04-FLG cannot handle. Do not use with liquids that tend to crystallize or solidify under operating conditions. Not for use on steam service as operating temperatures can easily exceed the limitations of the Teflon seals which are rated for 400 Deg F max. Consult factory for steam & gas service. The balanced piston design of this model accommodates large variations in inlet pressure. When ordered, if a set pressure is not specified, valves are set to the minimum pressure setting for the range selected. Valve can operate in any orientation: vertical, horizontal, etc. A high-pressure filter or strainer, which should be no coarser than #60 mesh, can be ordered from Stra-Val. See model SBS-10.
