The ALPI-NRV-LP is a low pressure non-return valve for medical gas distribution systems. This device is also used for an automatic activation of the 

Check valves are traditionally designed as a simple poppet/spring system where the spring is designed to equal the force created from the sealing area of the valve seat multiplied by the cracking pressure. Since the valve seat diameter in these types of valves are relatively small, less than 0.5 inches diameter, a low cracking pressure required

Find Low Pressure In-Line Check Valves related suppliers, manufacturers, products and specifications on GlobalSpec - a trusted source of Low Pressure In-Line Check Valves information. Description: The DFT® Restrictor Check Valve (RCV) is a versatile, all-purpose, spring-assisted, in-line check valve for applications that require higher cracking pressures to

pressure drop comparable to aircraft swing check valves. CLOSING Dead Tight Sealing at Any Pressure — Will hold air or fuel pressure indefinitely with 

Description: from 2 to 40 psi. Like the Basic-Check® valve, the Restrictor Check provides reliable, low maintenance service for a wide range of fluids and gases at various pressure/temperature combinations. The valve consists of a guard cage, spring, valve disc, Connection: Threaded. Flow (Cv): 5.8 to 90. Material of Construction: Stainless Steel.

The swing check valves are designed to keep pipeline safe from returning the medium. Swing check valve can be mounted to a pipe-line in horizontal position.

Clean Room Pressure-RegulatingValves for Water, Air, and Inert Gas. To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection.

Knowing that the terminal pressure drop ratio for this particular model globe valve is 0.7 we can now predict that if the inlet pressure was 300 psi, flow would choke at 210 psi pressure drop (300 X 0.7 = 210). In order to properly size control valves for gas service, it is necessary to know at what pressure drop flow will choke.

Parker provides the industry's widest selection of check valves, available in a variety of end connections. Our valves are used in a diverse range of applications, from air and fuel systems to load holding. Our check valves utilize a variety of media including oil, air, and water and are made from materials such as aluminum, stainless steel, brass, and carbon steel. Parker check

09/28 · Higher pressure on the outlet causes the valve to close. A check valve, also known as a non-return or one-way valve, is a two-port safety device that allows gas, steam, or fluid to flow in a single direction. Its primary purpose is to restrict backflow in a system. There are a variety of check valve stopping mechanisms, including a disc, piston

High-quality gas non-return valves protect against dangerous gas backflow. Low opening pressure - leak-tight elastomere sealing system - long service life.

Valve Body is made by Stainless Steel #316, suitable for fluid, air and oil. Larger diaphragm is more sensitive to pressure. Pressure Adjusting Range : 0.2 ~ 1.5 Kgf/cm2. Applied Temperature : -15 ~ 80 °C. Valve Body Testing Pressure : 16 Kgf/cm2. Maximum Applied Pressure : 10 Kgf/cm2.

The valve opens when system pressure approaches 1/2 psi to permit full flow with low pressure drop. As system pressure is relieved, the valve closes, retaining 

Jacksonville, Florida (September 16, ) Natural gas systems are designed to follow strict codes requiring secondary protection features to prevent over-pressurization. These systems are designed to eliminate single point of failure modes, however, systemic failure can even cause these redundant systems to fail under the most extreme conditions.
