Learn About Lead-Free Water Regulations and Compliant Solenoid Valves

Image
White Paper: Understanding the New Lead-Free Water System Regulations and Choosing Valves to Comply Lead is toxic and dangerous to human health. Regulations that restrict lead content in devices used for potable water are becoming more pervasive and present new design issues for valve users.

In the U.S., regulations governing lead content of the components of potable water systems have seen considerable changes as safety restrictions tighten. The federal law in effect since January 2014 dictates much lower lead content for certain systems and components than in the past.

This report outlines relevant sections of the law. It then focuses on the choices facing specifiers and purchasers who need to select important components of these systems — two-way solenoid valves — to comply. It considers the calculations that must be made to determine average lead content. Finally, it discusses the pros and cons of common valve materials (brass, lead-free brass, composite/plastic, and stainless st…

The EnviZion Hygienic Diaphragm Valve

Image
The EnviZion valve platform was developed to reduce the customer’s total cost of ownership (TCO).

Costs associated with installation, validation, operation, and maintenance are significantly reduced with the EnviZion valve.
Over 90% annual maintenance cost savings is achieved by reducing the time required to change diaphragms.No retorquing after thermal cycling reduces start up time and maintenance cost.Body seal reliability eliminates the potential for system contamination.Preventative maintenance intervals can be extended, saving time and cost.Production Capacity is optimized and unscheduled downtime and investigation costs are minimized For more information about the EnviZion Hygienic Diaphragm Valve, contact Tri-State Technical Sales by calling 610-647-5700 or visit https://tristatetechnicalsales.com.

Rupture Disc Designed Exclusively for Railroad Tank Car Overpressure Protection

Image
The Tanksert Rupture Disc was designed exclusively for railroad tank car overpressure protection, and to conform with ICC regulations.The Tanksert disc is a composite type, with flat seat sealing configuration. It is composed of an outlet ring for positive dimensional burst control and protection of the top section – a slotted metal top section which is the controlling burst member – plastic seal which isolates top from the tank media and prevents leakage - vacuum support which prevents seal from becoming damaged, should a pressure surge occur during transit or unloading. The vacuum support is also specially designed with an off-set section to assist in positive alignment during installation.

These discs are exceptionally accurate and fit standard threaded or bolted railroad tank car safety vents.


The Tanksert disc is a six (6) piece construction. The first five (5) pieces are permanently spot welded together.


Is the controlling member of the disc assembly, constructed of 316 S.S.Is t…

8 Selection Criteria for Choosing Differential, Pressure, or Temperature Switches

Image
When selecting differential pressure switches, pressure switches, or temperature switches there may be more than one choice, so the lower cost option is usually the best choice. There are some general guidelines for considering cost. For instance, in general a NEMA 7 rated switch will cost more than a NEMA 4 rated switch, a stainless steel housing will cost more than a die cast aluminum or brass housing, and a dual chamber design more than the standard housing.
Here are 8 Selection Criteria for Choosing Differential Pressure or Temperature Switches
Does the applications require an Explosion Proof (NEMA 7) housing or a Watertight (NEMA 4) housing?Do you need single or dual set points?Do you need fixed or adjustable dead band?Do you need an adjustable set point switch or a factory set only switch (this step is only for Pressure Switches)?Select the appropriate switch model listed in the step 5 boxes in the pressure, differential pressure or temperature switch selection charts. This sele…

What Are Flame and Detonation Arresters, Pressure & Vacuum Relief Valves, and Blanket Gas Regulators?

Image
PILOT OPERATED RELIEF VALVES Pilot operated relief valves serve the same primary purpose as pressure/vacuum relief valves, but with better performance characteristics than weight or spring loaded valves. Lower leakage and better flow performance make a pilot operated valve the solution when the focus is product conservation, expanded tank working pressure range, and reduced fugitive emissions. A pilot operated relief valve pro-vides the maximum available leakage control technology as specified in the Clean Air Act of 1990.

PRESSURE/VACUUM RELIEF VALVES Pressure/vacuum relief valves are protection devices typically mounted on a nozzle opening on the top of a fixed roof atmospheric storage tank. Their primary purpose is to protect a tank against rupture or implosion by allowing the tank to breathe, or vent, when pressure changes in the tank due to normal operations.

BLANKET GAS REGULATORS Blanket gas regulators can provide both pressure and fire protection for storage tanks by supplying a…
