EXPANSION JOINTS
Proco Products are leading expansion joint manufacturers with an extensive inventory of expansion joints for piping and ducting systems. Our movement expansion joints are manufactured to have the ability to protect your equipment against a variety of stressors while also being low maintenance and durable for maximum efficiency. Proco Products manufacture expansion joints for industrial and commercial installations using pumping, piping or ducting which requires expansion or movement joints to deal with thermal expansion, vibration or ground movement. With a variety of designs in rubber, stainless steel or polytetrafluoroethylene (PTFE), our high-performance expansion joints ensure safe and reliable operations supporting system integrity, mitigating fatigue and reducing maintenance downtime.
Check out our extensive range of expansion joints below.
Our Expansion Joints
Proco rubber expansion joints offer inherent flexibility and strength designed to meet the most challenging temperature / pressure requirements. Known for their capability to withstand extreme environments, our rubber expansion joints are commonly found in harsh applications such as water and wastewater, pulp and paper, chemical processing, mining, metals and pumping applications.
Our PTFE expansion joints have advantageous properties for the chemicals processing industry to protect against corrosive substances. As a non-reactive synthetic material, Polytetrafluoroethylene creates high performing expansion joints that perform within extreme industrial environments.
Our expansion joints use a combination of rubber and fabric reinforcement to add flexibility to industrial ducting systems / fan connections. Ducting expansion joints are strengthened with vulcanized reinforced fabric to withstand large movements and isolate vibration and noise.
CHECK VALVES
Flow check valves in pipelines permit liquids and gases to flow one way in a single direction only and prevent the flow reversing. The correct flow pressure forces the check valve open whilst reverse flow causes the valve to close.
Flow check valves open at a designed minimum flow, or cracking pressure, for the valve to begin to operate. Check valves protect systems from pressure surges that may cause damage to pumps and pipework and help efficient operation. Check valve suppliers provide several types of valves, these include ball valves or metal flap check valves in which a disc pivots to prevent reverse flow. Proco Products is a check valve manufacturer specializing in fabricating rubber which has the advantage of not only being durable and effective, but also reduces the likelihood of common maintenance problems seen in metal valves.
Rubber duck bill check valves use a rubber diaphragm which remains closed until fluid or gas flow pressure is applied to open it. Unlike their metal swing or flap check valve counterparts, rubber check valves cannot rust, seize, or bind, typically increasing reliability and longevity. Similarly, rubber check valves do not suffer from mechanical wear, a factor which can negatively influence check valves manufactured from other materials.
Proco Products is a leading manufacturer of rubber check valves, these are fully passive devices requiring neither maintenance nor any source of outside power or manual assistance to operate. Proco Products is also a rubber check valves supplier offering new and replacement valves that are interchangeable with flap type check valves eliminating seizing, rusting or binding in unwanted positions. Rubber check valves are made to work with ultra-quiet operation, do not warp or freeze and are designed to prevent standing water and eliminate trapped solids.
Proco Products manufactures check valves, industry approved, for water and wastewater, pulp / paper and mining. We supply check valves for use in stormwater applications, sewage treatment plants, outfalls, tidal and pre-existing pipelines such as manholes and vaults.
