Clippard releases 8 mm series micro proportional valve
Clippard has released an 8mm series micro proportional valve . These proportional , directacting valves provide precise , linear control for accurate dosing and flow regulation in critical applications . With low power consumption , they offer excellent energy efficiency while maintaining quiet operation and minimal vibration . Their versatile design makes them suitable for a wide range of medical , diagnostic , and industrial applications .
Standard products offered will fit the needs of most applications , however , this series can be fully customised according to the user ’ s unique requirement : ideal for compact assemblies ; eliminates downstream pulsations ; smooth proportional delivery ; low current power / low to no noise ; exceptional variability of flow vs . command current ; tiny package with a robust design ; and highly customisable performance .
Danfoss launches EVR and NRV safety valves
Danfoss is proud to announce the release of its new and reliable EVR and NRV Safety Valves , approved to meet UL 60335-2-40 and UL 60335-2-89 standards . As the industry faces tighter safety regulations , the Danfoss EVR solenoid valves and NRV check valves provide a solution for separating flammable refrigerant charges ( A2L , A2 , or A3 ) in case of leaks , thereby reducing the total releasable charge in higher capacity systems . By meeting the stringent UL requirements , these Danfoss valves are a critical component for manufacturers , installers and operators striving for compliance and enhanced system safety . The key features and benefits are : UL 60335-2-40 & UL 60335-2-89 Compliance : Designed to fully comply with the new safety standards , ensuring safe operation of systems using flammable refrigerants ; Enhanced Leak Safety : Effectively isolates flammable refrigerants during leaks , mitigating potential hazards and improving overall system safety ; Fail- Safe Operation : Features automatic shutoff to prevent refrigerant backflow and leakage , providing an additional layer of protection during power failures ; and Versatile Application : Ideal for a range of HVAC and refrigeration systems , offering flexibility across multiple system designs and requirements . Danfoss ’ EVR and NRV valves are available in multiple sizes , ensuring they are adaptable to a wide range of system configurations and needs . The valves are easy to install , minimising disruption during installation and offering a reliable solution for maintaining safety standards in HVAC and refrigeration systems .
Patented modular design by Fluorten Zero leakage
Nowadays , standard seal designs are challenged to almost impossible tasks . With LNG and H2 becoming more and more popular as clean fuels , it is necessary to eliminate the leakage of methane . In addition to protecting the environment , a leak-free valve is also a serious safety feature when operating highly flammable gas like H2 . Fluorten developed a special , patented gasket for cryogenics , which incorporates radial and frontal sealing elements in a modular design , aiming to reduce leakage and dangerous emissions . Radial and frontal components can be made with different materials : Victrex CT™ 200 ( Cryo-PEEK ) is the perfect polymer for
both radial and frontal parts thanks to its elasticity at -269 ° C ( -452.2 ° F ); PCTFE and modified PTFE ; and further low-porosity materials . Standard radial seals work only on diameters . Compared to radial-axial seals , they undergo relevant changes when working at low temperatures : diameters shrinkage , lowered elasticity , and higher hardness . Radial-axial seals offer several advantages instead : no shrinkage : frontal sealing capability stays the same , if diameters change due to temperature variation ; double barrier : if the OD of the radial seal is not enough , the frontal seal works as an additional barrier ; zero leakage as shown by tests with helium ( leakage is 10 times lower than in standard radial seals ); excellent performance compared to standard seals ; and any sealing system can take advantage of this design . www . valve-world . net Valve World February 2025
