Technical details and quality points of interest for our valve offerings:

  • Trunnion Ball Valves: These valves feature a fixed ball that is supported by trunnion bearings, ensuring optimal sealing and reduced torque requirements. They are suitable for high-pressure and large-diameter applications. Calvary can offer a full product line of welded body ball valves, as well as our new design of "double piston effect" ball valve
  • Floating Ball Valves: With a freely moving ball, these valves offer excellent sealing performance and low operating torque. They are widely used in various industries for their versatility and reliability.
  • Swing Check Valves: Designed to prevent backflow, swing check valves utilize a hinged disc to allow fluid flow in one direction while blocking reverse flow. They are known for their minimal pressure drop and reliable operation.
  • Piston Check Valves: Featuring a piston that moves up and down to regulate flow, these valves provide efficient and quiet operation. They are commonly used in applications where a tight seal and reliable performance are crucial.
  • Lubricated Pressure Balanced Plug Valves: It features a plug-shaped closure element, which rotates within the valve body to open or close the flow passage. This particular valve is designed with a lubrication system and pressure balancing mechanism to enhance its performance and reliability. The Lubricated Pressure Balanced plug valve is certified to Nace MR 01 75 standards. Nace MR 01 75 is a material standard issued by the National Association of Corrosion Engineers (NACE) that sets requirements for the selection and use of materials in environments where corrosion is a concern.
  • Wafer Style Piston Check Valves:Compact and lightweight design. Typically made of cast iron, carbon steel, stainless steel, or other suitable materials.Available in various sizes and pressure ratings. Check valves operate automatically, allowing flow in one direction and preventing backflow. Wafer style piston check valves offer a compact design, making them suitable for applications with limited space. The wafer-style flange connections simplify installation and maintenance processes.
  • Lug Style Butterfly Valves: These butterfly valves feature lugs on their body, allowing them to be installed between flanges without needing additional hardware. They provide reliable isolation and control in various applications.
  • Wafer Style Butterfly Valves: Wafer-style butterfly valves are designed to fit between pipe flanges, offering a compact and cost-effective solution for fluid control. They are widely used in HVAC, water, and wastewater applications.
  • High-Performance Butterfly Valves: Engineered for demanding applications, high-performance butterfly valves offer exceptional flow control, reliability, and durability. They are suitable for high-pressure and high-temperature environments.
  • API 6D Gate Valves: Compliant with API 6D standards, these gate valves ensure robust sealing and excellent flow control. They are widely employed in the energy industry, offering reliable performance even in the most demanding conditions.
  • Slab Gate Valves: Full-bore design with a flat gate that slides between two seats to control flow. Available in various sizes, typically ranging from 2 inches to 48 inches or larger. Gate valves are operated by a turning motion of the stem, which raises or lowers the gate to control flow. Slab gate valves offer a full-bore design, minimizing flow restrictions and pressure drop across the valve. The flat gate design with two seats ensures bidirectional sealing, preventing leakage in both flow directions.
  • Expanding Gate Valves: The gate expands or contracts to provide sealing against the seats. It is designed with a gate-shaped closure element that expands and contracts to open and close the flow passage. The gate is typically made of metal, and it expands against the seats when closing to provide a tight seal.
  • Wedge Gate Valves: Known for their wedge-shaped gate design, these valves provide a tight seal and high-pressure capabilities. They are widely used in pipelines and industrial processes, offering reliable and efficient flow control.
