Pinch Control Valves for Regulating Flow of Slurries, Abrasives, Fibrous and Corrosive Media

Red Valve Control Valves offer maximum durability with precise control and virtually no maintenance.  A heavy-duty pinch mechanism positions the sleeve for accurate control over a wide flow range. 

Red Valve Control Pinch Valves have no packing to maintain or seats to wear, no fugitive emissions and no need for expensive body alloys. Variable orifice and cone sleeves can be specified to further enhance control performance and match the exact CV level desired. True feedback positioning is accomplished through the direct linkage of the pneumatic positioner to the valve stem shaft, with no splitting of the positioner output. Red Valve Control Products are available with pneumatic, electro-pneumatic, or digital positioners to link up to all control systems.

Jordan Valve's Sliding Gate Seat Technology for Regulators and Control Valves

Jordan Valve's Sliding Gate Seat is an excellent alternative to traditional control valve trim designs. The benefits are easy to see. They include: 

1. Straight Thru Flow – The control element is perpendicular to the flow, resulting in less turbulence and superior trim life.
2. Constant Contact in Seats – The disc and plate are in constant contact. Therefore, there is no valve ‘chatter’, less mechanical wear and greater stability at the low end of the stroke. The constant contact results in a self-lapping and self-cleaning action. Jordan Valve sliding gate seats wear in – they don’t wear out.
3. Easy Maintenance – There is only one moving part in the Sliding Gate Seats. The seats are not pressed or screwed into place, so removal is easy. Cv values are interchangeable and control valve action is easily changeable.
4. Short Stroke – In regulators, this results in faster response to input signals, less droop (greater accuracy), and longer diaphragm life. In control valves, the short stroke of the sliding gate seat results in less packing wear. Additionally, smaller actuators can be used resulting in lighter weight, smaller envelope dimensions and less air consumption.
5. Seat Materials – Jorcote is the standard seat material. Jorcote is harder than stainless steel and provides excellent wear, erosion, & galling resistance. It has a lower coefficient of friction than Teflon; providing higher pressure drop capability and less offset. Jorcote seats perform in temperatures from sub-zero to 550°F (288°C). These seats have been lab tested to 1,000,000 full stroke cycles in 70 psi steam and maintained ANSI Class IV leakage while displaying negligible wear.
6. Disc Plate Overlap – The disc and plate overlap by 1/32” (0,8mm) around each orifice. This creates an area of closure, not line of closure, resulting in better shutoff for a longer period of time, reducing waste and lowering costs.
7. Multiple Orifice Design – The multiple orifice design of the sliding gate seat dissipates the wear energy and downstream flow, resulting in longer trim life and quiet operation.

The Unique Challenges of Measuring Steam Usage for Colleges and Universities

ExactSteam™ V-Cone® Flowmeter

Steam poses a unique challenge for colleges and universities.

Many schools want to accurately track, and then internally bill, for steam usage in each of their buildings as part of a wider effort to improve resource management. However, traditional steam metering technologies tend to be a less than optimal choice.

Most times, it’s necessary to place campus steam meters in the basements of buildings where there isn’t a lot of room for piping. That causes issues because flow meters typically require significant runs of straight pipe upstream and downstream of the meter to work correctly.

School administrators also encounter issues by trying to measure steam usage during the low-demand summer months. Common vortex meters, which contain a shedder bar mounted across the diameter of a pipe to measure flow, work well at higher flows. When it comes to low flows, however, they can stop working completely (i.e., low flow cutoff problems). Differential pressure (DP) flow meters coupled with the proper electronics, by comparison, can push the low flow cutoff value downward. However, most DP meters can’t get around the straight-run requirements.

McCrometer’s ExactSteam solution is designed to overcome those hurdles.

The ExactSteam V-Cone Flowmeter works well with short straight-pipe runs, so it addresses the lack of space issues faced by colleges and universities. It also measures steam across the entire range, performing better at lower flows.

The High Cost of Low Flow Cutoff

Steam system operators can pay a steep price for generating product that passes through a meter but fails to get measured. Also known as low flow cutoff, those losses are a function of the turndown ratio of flow meters. The ratio — defined as the maximum measurement capability of a device compared to its minimum — dictates how wide a flow spectrum can be measured. On campuses, this creates a major issue because demand for steam in the colder weather can be extremely high compared to off-peak times.

ExactSteam is a DP-style flow meter that can be adjusted for colleges during winter months. It contains McCrometer’s established V-cone flow meter combined with a newer electronics package to aid in the downward adjustment of the turndown ratio. A growing number of college campuses, especially larger schools, are seeing the benefits of ExactSteam and adopting the technology.

Some examples include:

Case Study #1 - An East Coast University Steam Operation

This school designed its system to measure from 84,000 lbs/hr to 8,400 lbs/hr, which accounted for a 10:1 turndown ratio and velocities of 420’/second to 42’/second. After the meter was installed, system operators determined their actual flow range was 20,000 lbs/hr to 1,000 lbs/hr (a 20:1 turndown ratio) and velocities were 100’/second to 5’/second.

Because flow rates were overstated, the university dropped below the low flow cutoff and wasn’t measuring at all during the off-season.

The solution: Purchase another meter with a larger cone that would produce more differential pressure at the correct flows. The school has since installed an ExactSteam V-Cone Flowmeter.

Case Study #2 – A University Hospital Using Both Condensate And Steam Meters

During the winter, the steam meters were always measuring more steam than the condensate meters.  The difference was justified because the condensate meters were not capturing steam usage of the autoclaves.  However, during the summer, the condensate meters were measuring more than the steam meters, which was impossible.

The steam meter was designed for flows from 14,000 lbs/hr to 1,400 lbs/hr.  During the summer months the hospital flows frequently dropped below 1,400 lbs/hr, which was below the low flow cutoff.  It was also determined that their highest flow during the summer was 5,000 lbs/hr.  The hospital needed more turndown and a lower flow range.

The solution: The ExactSteam V-Cone Flowmeter was installed.  It was designed for flows from 6,000 lbs/hr to 300 lbs/hr and was able to fit in the basement between two elbows.

Well Positioned For Campus Use

Key aspects of McCrometer’s ExactSteam solution include: a complete flow meter for steam metering, factory-configured for energy metering or mass flow; the ability to measure saturated (dry), superheated, and unsaturated (wet) steam; the V-Cone acts as its own flow conditioner by disrupting all centralized flow disturbances; signal stability allows it to measure a wider range of flow than other meters, minimizing pressure loss; and minimum installation requirements, so retrofitting and new installations are easier.

Because of the inherent conflicts, traditional steam metering technologies are not a good fit for many colleges and universities. However, there are solutions available to campus steam system operators to capture readings from most — if not all — of their steam production, even in less than ideal conditions.
