About JACO

JACO is a manufacturer of fluid-handling components, with a product line that includes check valves, fittings, and tubing connectors designed for corrosive and high-purity applications. The brand is recognized for its use of engineered thermoplastics such as PVDF (polyvinylidene fluoride) and for offering configurations that suit chemical processing, water treatment, and industrial instrumentation. JACO check valves, specifically the ball check valve series, are constructed with a PVDF body and are available with either 316 stainless steel or PTFE ball materials, paired with 316 stainless steel seats. These valves are designed for inline horizontal installation and feature male NPT (MNPT) connections on both ends, with pipe sizes ranging from 1/8 inch to 1/2 inch. The PVDF body provides resistance to a wide range of chemicals, including acids, bases, and solvents, and offers thermal stability up to approximately 150°C (302°F) depending on pressure conditions. The 316 stainless steel ball and seat options deliver durability in abrasive or high-pressure environments, while PTFE ball variants reduce friction and are suitable for applications requiring low torque or where media compatibility with metal is a concern. JACO ball check valves are typically rated for pressures up to 150 psi (10.3 bar) at ambient temperature, though exact ratings depend on the specific model and operating conditions. The valves are designed to prevent backflow in piping systems, with the ball sealing against the seat under reverse flow conditions. JACO does not publish a formal IP rating for these valves, as they are intended for use in dry or protected environments rather than direct exposure to moisture or dust. 3G Electric stocks multiple SKUs of JACO PVDF ball check valves, including both 316 stainless steel and PTFE ball variants, in pack quantities of five per SKU. This allows procurement specialists to source consistent components for maintenance or new installations without minimum-order complications. The product range covers common pipe sizes (1/8, 1/4, 3/8, and 1/2 inch), enabling engineers to match valve dimensions to existing piping systems. 3G Electric provides logistics support for global shipments, ensuring that JACO check valves are available to industrial buyers worldwide. For technical buyers, the key considerations when selecting a JACO ball check valve are the ball material (316 stainless steel for higher strength and wear resistance; PTFE for chemical inertness and lower friction), the pipe size compatibility, and the operating pressure and temperature of the system. The valves are not recommended for vertical installations unless specified, as the horizontal orientation is integral to the ball seating mechanism. JACO does not publish certifications such as NSF or FDA for these valves, so buyers should verify compliance with specific industry standards independently. Overall, JACO PVDF ball check valves offer a straightforward, corrosion-resistant solution for backflow prevention in moderate-pressure fluid systems.
