Please use a more up to date browser. There are two basic types of valves used with gases; diaphragm packless and packed. Star-Regulator Bottle-connection on backside Bottle pre-pressure 200 bar. Whenever there is a change in inlet pressure, there will be a corresponding change in outlet pressure. together the optimum regulator for you.
Many skilled technicians would expect the outlet pressure to decrease concurrently, but instead, the outlet pressure rises.
Learn how easy-to-use gas panels and an overall more efficient gas distribution and delivery system can help laboratories, refineries, and other facilities drive down maintenance costs. Manual controls are valves that have been designed for direct connection to a compressed gas cylinder valve outlet. Specifications Conversely, if the inlet pressure increases, the outlet pressure decreases. Two-stage pressure reduction is a good solution for minimizing supply pressure effect in practically any application. In an application using one gas cylinder to source multiple operations under the same outlet pressure, either option may be sufficient. Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates. The intention of this regulator design is to minimize the area on which the high inlet pressure can act. One-stage regulators perform the same service as two-stage regulators, but in one step. Gas distribution system advisorsare available to evaluate your existing gas distribution systems and identify opportunities for improvement, and associates at your local Swagelok sales and service center can also advise you on component selection.

Contact Us. To demonstrate how SPE impacts a balanced poppet regulator, envision gradually decreasing the inlet pressure as demonstrated previously with the unbalanced poppet design. Please sign in to view account pricing and product availability. The outcome is an increase in outlet pressure due to SPE. Because the first-stage regulator experiences the large inlet change and outputs a smaller outlet change, the second-stage regulator reacts only to the small inlet change from the first stage and shows minimal pressure decrease on the outlet side. This excessive setup amounts to three-stage regulationwhich is unnecessary for most applications. -, {{product.productPrice.formattedPriceMax}}. Specialty gas regulators are used to reduce high-pressure specialty gases from cylinders or process lines to lower pressures suitable for use.

To calculate the variability of outlet pressure for a two-stage regulator setup, the inlet pressure difference is multiplied by the SPE of each regulator. Cylinder scales are designed to provide a positive indication of the amount of product remaining in the cylinder. Still, SPE will always be present in regulators used in gas systems, regardless of poppet design. Learn about common challenges that can hamper the safety and efficiency of important gas distribution systems and how a professional evaluation of those systems can provide long-term value. A regulators SPE is typically provided by the manufacturer. Low Pressure Propane Regulators
Monel and Hastelloy bodies are available upon special request. A pressure regulator does not control flow, but precise control of pressure is required for precise flow control. Droop is an issue for every pressure-reducing regulator. Line regulators and some regulators used on liquefied gases have only a delivery pressure gauge, because in these applications the inlet pressure is virtually constant. Information for specialty gases found on this website includes recommended pressure regulators for best service. Brass Body Piston pressure regulator with self-relieving design, hollow bolt and pivoting ring piece. outlet Pressure: 0 bar - 200 barOrifice diameter: 0.13 in. Some are designed as housings that accept replaceable cartridges containing the adsorbing materials, others are sealed units that are replaced completely, while others require no replacement or can be regenerated in place. A filters rating is usually expressed in microns, referring to the maximum size diameter that will pass through the filter. The degree of outlet pressure variation for a regulator can be estimated with the following formula: One of the most common types of regulators is a spring-loaded pressure-reducing regulator. For example, if a regulator is described as having a 1:100 or 1% SPE, for every 100 psi drop in inlet pressure, the outlet pressure will increase by 1 psi.

If this is the case, set-up the first-stage regulator near the gas cylinder and the second-stage regulator on each of the process lines or at the point of use. Notice how the effect on the outlet pressure is dramatically lessened from the previous regulator arrangements. Flowmeters are used in fluid systems to indicate the rate of flow of the fluid. To be used for a 300 bar gas supply system Each regulator controls the inlet pressure variation to a certain degree, but together, the two regulators keep the outlet pressure very close to the original set point. Technical Questions? On the other hand, applications that require a gas cylinder to supply multiple operations with different pressures will need to use two single-stage regulators to make a two-stage regulator system. Gas cylinder regulators made of brass are recommended for non-corrosive specialty gases. Regulators maintain constant pressure by providing high accuracy, precision control, and maximum stability under the most adverse conditions.

In an unbalanced poppet design, the inlet pressure pushes up on the poppet and applies pressure to a portion of the poppet equal to the seat area. At an inlet pressure of 1160 psig (80 bar), the outlet pressure is 43.5 psig (3 bar). {{#i!=(product.specData.length-1)}} Compact pressure regulator, Push-in connector for hose 10, G 1/4, Two-stage regulators are generally used whenever the compressed gas cylinder pressure exceeds 1000 psig. Packed valves are designed with a packing gland that creates a seal on the valve stem. Two single-stage regulators in series will yield minimal SPE at a lower cost. In these systems: With the regulator controlling outlet pressure from a gas cylinder, supply pressure effect is a phenomenon that will always be present. The first-stage regulator will encounter an increase in outlet pressure as the gas cylinder empties and inlet pressure decreases. A cylinder scale is used to monitor the contents of a liquefied gas cylinder feeding a critical batch operation where a lack of gas during the run would cause the batch to fail. This is accomplished by the installation of a valve on the outlet side of the regulator in conjunction with a flowmeter or electronic mass flow controller.
