  • in Ball Valves

    Gemini Valve manufactures motorized ball valves, pneumatic ball valves and manually operated ball valves in a three valve series. Their product line includes the general industrial series (brass, carbon steel, stainless steel, monel and alloy), the instrumentation series (brass ball valves and stainless steel ball valves), maintenance-free series (brass and stainless steel), 3 piece ball valve series (stainless steel), diverter series (carbon and stainless steel), and the wafer ball valve series (stainless steel). The company's line of valves also includes spring-loaded ball valves, check ball valves, actuated ball valves and electric ball valves.

  • in Brass Ball Valves

    Gemini Valve designs and manufactures motorized, pneumatic and manually operated brass ball valves in three valve series'. The 76 Series are the simplest and most economical ball valves. The 86 Series standard port and 96 Series full port models are available when maximum flow is needed. Gemini pneumatic ball valves are designed to operate using an air supply of 50 - 125 psi.

  • in Motorized Ball Valves

    Gemini Valve offers 76, 86, and 96 general industrial series motorized ball valves. These valves have temperature ranges from -50 to +450°F, cold working pressures of up to 720 PSI, vacuum ratings of up to 20 Microns, and saturated steam of up to 150 PSI. They feature internal limit switches for precise 90° rotation and are ideally used for various On/Off applications.

  • in Pneumatic Valves

    Gemini Valve manufactures numerous pneumatic valves in a variety of sizes and configurations. The 76, 86, and 96 Series, for general industrial use, come in 0.25" to 2" diameter sizes and support a 720 psi cold working pressure (C.W.P.). Meanwhile, the 82 Series tube compression valves offer an alternative to high pressure models for applications which require 1,000 psi or less. Finally, with 300# class flanges, the full port steel Series 98 wafer ball valves are rated to 720 psi at 100 degrees Fahrenheit or 300 psi at 321 degrees; with 150# flanges, they are rated to 275 psi at 100 degrees and 200 psi at 365 degrees.

  • in Stainless Steel Ball Valves

    Gemini Valve produces valves in 316 stainless steel body materials. Stainless steel valves include 76, 86 and 96 general industries series of valves with NPT and BSPT range from 1/4" to 2", 82 instrumentation series of tube compression valves, 87 series of high cycle ball valves, 89 three piece ball valve series, 309 diverter series of 3-port ball valves, and 98 series of wafer style ball valves.
