The assembly integrates a bronze body globe valve with brass trim and a spring return pneumatic actuator, providing reliable, fail-open control of water or compatible fluid flow. Key specifications include a 1\/2-inch union angle end connection, a flow coefficient (Cv) of 1.3, and an equal percentage flow characteristic that provides stable modulating control across a wide range of system pressures. Licensed HVAC controls technicians and mechanical contractors are the primary installers of this assembly.\u003c\/p\u003e\n\u003cp\u003eThis valve assembly is suited for terminal unit control in commercial and light industrial HVAC systems, including fan coil units, unit ventilators, and similar hydronic applications requiring modulating two-way flow control. The union angle body configuration simplifies field installation and service access. The spring return actuator ensures the valve returns to the normally open position on loss of pneumatic signal, supporting fail-safe system design. The 3-7 psi spring range is compatible with standard pneumatic control branch lines common in existing DDC-pneumatic hybrid and legacy pneumatic control systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-way normally open configuration provides fail-safe open operation on loss of pneumatic signal\u003c\/li\u003e\n  \u003cli\u003eEqual percentage flow characteristic delivers stable modulating control across the operating range\u003c\/li\u003e\n  \u003cli\u003eBronze body with brass trim globe valve offers corrosion resistance suitable for hydronic service\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch union angle end connections allow straightforward installation and in-line serviceability\u003c\/li\u003e\n  \u003cli\u003eSpring return pneumatic actuator operates on 3-7 psi control signal\u003c\/li\u003e\n  \u003cli\u003eCv of 1.3 sized for low-flow terminal unit applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation globe valve assembly for pneumatic building automation and HVAC hydronic control systems requiring a 1\/2-inch, 2-way normally open modulating valve with a 3-7 psi spring return actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC controls technician or qualified mechanical contractor familiar with pneumatic control systems and applicable mechanical codes. Shut off and isolate the hydronic circuit and relieve system pressure before disconnecting or installing the valve assembly. Verify the pneumatic control air supply pressure and branch line range are compatible with the 3-7 psi actuator spring range before connecting the control line. Do not exceed the valve body pressure and temperature ratings for the system fluid.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 2-Way Normally Open\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection Type\u003c\/strong\u003e: Union Angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Coefficient (Cv)\u003c\/strong\u003e: 1.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Characteristic\u003c\/strong\u003e: Equal Percentage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrim Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Globe\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Spring Return Pneumatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Spring Range\u003c\/strong\u003e: 3-7 psi\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHNEIDER ELECTRIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VK-7211-201-3-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51524953342258,"sku":"VK-7211-201-3-2","price":407.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2cb93f50b0cad8d54dd89875b676309f.jpg?v=1785462188","url":"https:\/\/voomisupply.com\/products\/schneider-electric-vk-7211-201-3-2-pneumatic-globe-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
