5000 PSI – Low Noise – Fine Control

/in

Ongoing field trials have validated the HBGV performance for several months. The newest installation in the test facility of a major pump manufacturer has been well-accepted as the HBGV outperforms the back pressure control valve it replaced. Daily use has subjected the valve to pressures up to 3600 psi.

We have been stalking “bigger game”, and today we bagged it: 5000 psid and over 400 gpm. The HBGV was conceived to precisely control choked flow, and it did that. With the valve throttled below 10% open, SPL measured just above 80.

So where do you find a 5000 psi flow test facility? You create one, with the help of a company in the business of servicing hydraulic fracturing skids. We adapted the 5000 RTJ flanges to 1502 hammer union fittings required in the 15ksi world. Next, the HBGV was connected to a manifold in front of the angle-pattern chokes in place for pump testing:hp-test-plumbingThe green intake pipe in the picture originated at the output of a piston pump driven by diesel motor supplying 1200 HP.

Up to this time VSI has only offered field trial valves, and now we’re ready for a RFQ. Please contact us with your severe service control valve problem/application to find out why the HBGV would be a cost effective solution.

Back at the beginning, prior to the official launch of VSI, we were recognized in the press for our pursuit of a better way to control choked flow. i2E in Oklahoma provided the tools to get VSI launched, and this feature in the business pages of the two major newspapers helped. When ASME picked up the story, our plans were given a big boost. SmartBrief 2014

With two valves in field trial and manufacturing preparations in work, we are comfortable with how the follow-up to the story in the December 21, 2014 Tulsa World is unfolding.141221 – VSI

First Delivery for Field Trial

/in ,

VSI delivered the first Helical Bevel Gear-drive Valve, the HBGV, on Thursday, February 18, 2016. The valve will be installed as a pump back pressure regulator on an injection skid manufactured by Global Production Systems, GPS, in Shawnee, Ok.

GPS is a leader in injection systems design and manufacturing that include instrumentation and control systems permitting the multi-stage centrifugal pumps to operate most efficiently.

While this marked a significant milestone for VSI in the development of the HBGV, the near future looks bright as we actively seek other field trial applications for a 5,000 psi rated choked flow control valve with a flow coefficient up to 60.

We have two API 6A compliant valves and one Class 1500 RF flanged valve in production, ready soon to drop in and replace problem-plagued 2″ conventional control valves. The electronic actuation system is capable of 1% accuracy with 20:1 rangeability. HBGV SN160201 Assembled

Flow Lab Tests Complete – Performance Confirmed

/in

IMG_20160128_111431559The final round of lab testing wrapped up this week. Flow test data gathered at the Radford Company valve test facility confirmed predictions of CFD simulations made prior to the launch of VSI. Maximum Flow Coefficient was measured to be 75 in turbulent flow. The HBGV1 was confirmed to have negligible pressure recovery in the valve and an effective CsubV of nearly 60 in full choked flow as pressure recovered far downstream.

Flow Testing the HBGV

Flow testing of the HBGV began at Total Valve Systems in Broken Arrow, OK. The 2″ control valve was confirmed to have a flow coefficient above 60 Cv, the primary performance specification. Lobo Engineering PLC is processing the 136,000 data points to establish the inherent characteristic and choked flow performance ratings.

Assembly of the First HBGV

DSCF2769The first of five pre-production severe service control valves is prepared for flow testing and field trials. From the 3-D printed patterns for the internals to the rigorous CNC machining of the Body and Hub, the manufacturing process was complex. Eight contractors were coordinated by VSI to produce the valve in three months.
