McWane Plant & Industrial (MPI) products

Designed for years of dependable service, the superior design of our butterfly valve provides ease of adjustment along with the ensured dependability expected in any distribution system or plant installation. Our butterfly valve has a 100% bubble tight seal via a 316 stainless steel ring located in the body, and rubber seat located on the vane. The rubber seat provides a `zero leakage` alternative to metal-seated valves. For pump station and treatment plant applications, butterfly valves offer flow control advantages (such as throttling) over gate valves,and are much more economical. Our butterfly valves are manufactured in accordance with the American Water Works Association (AWWA) C504 standard. Butterfly valves are constructed of ductile iron, stainless steel, rubber seats & seals. The strength of ductile iron along with stainless steel components provide corrosion resistance for buried service applications.

Hard, stainless steel disc edge sweeps away tuberculation from the valve seat. On valve sizes 3"-24" the EPDM seat is vulcanized to the full interior of the body and protects body from abrasion by suspended particulate. On valve sizes 30"-36" the seat is easily replaced or adjusted in the field utilizing common hand tools.

MPI offers a selection of options for valve operation, including gears, handles, and electric acuators.

MPIs line of rotating disc gate valves has been utilized successfully since 1908 in water/wastewater treatment plants and water lines all over the United States. If you are looking for an extended life valve, this valve is your choice for generations of service. MPIs rotating disc gate valves clean themselves with every operation. Deposits are removed in travel, so nothing builds up on the seating surfaces that could cause leakage. Discs are free of pockets that could collect solids. The rotating action of the discs creates a different seating position each time the valve is closed. Uneven or excessive wear is prevented, so the sealing components remain smooth and operational years longer without maintenance or replacement. Since the discs rotate, they cannot foul on the body guides.

During the 1980’s, the waterworks industry was introduced to the resilient seated gate valve and Kennedy Valve Company was at the forefront of this industry wide movement.  Today we offer both our KS FW AWWA C509 Full Wall and KS RW AWWA C515 Reduced Wall resilient seated gate valves, embodying the latest valve technology for simplicity, durability, and superior performance.

MPIs Swing Check Valves are designed and manufactured in conformance with AWWA C508. Under certain circumstances where it is desirable to have more positive control of the closing on the disc, the valves can be supplied with either lever-and-spring or lever-and-weight. Swing check valves are used for the prevention of backflow in water systems where there is the possibility of a pollutant in the user`s system back flowing into the potable water system. They are self-contained, free-swinging disc style which can be purchased with an outside lever and weight or outside lever and spring options conforming to AWWA C508 standards. The valves can also be purchased with outside air or oil cylinders when required by customer requirements or project specifications. Valves sizes 2"-24" can be ordered with double lever arms. Valve sizes 30" and larger come with standard double lever arms.

The KEN-FLEX resilient-hinged check valve provides reduced maintenance and faster closing than most traditional swing check valves. The rubber-encapsulated flapper assembly is the only moving part and is easily accessed through a full-size cover with the valve in line. The resilient flapper material makes KEN-FLEX" ideal for "dirty water" applications, and the fast-closing action is ideal for surge prevention. The optional position indicator is spring loaded and provides the added benefit of accelerated closing speed.

MPIs Eccentric Plug Valves are designed for consistent performance, durability and longevity. Built to the AWWA C517 standard, the Eccentric Plug Valves are available in sizes 3"-48" for 100% port with a variety of end connections. A reliable and engineered product capable of bi-directional flow at fully rated pressures. Dependable in a variety of service applications.

MPIs NRS style ductile iron/stainless steel mud valves are designed primarily for use in settling tanks of water and wastewater treatment plants. They are available in both ductile iron and stainless steel bodies. Their intended use is to drain tanks for maintenance or cleaning. Mud Valves are furnished with a 2” square operating nut; however, they can be supplied with optional extension stem or handwheel. The valve uses a Buna-N resilient seat on the plug. The ductile iron/stainless steel body assembly features ASTM A276 stainless steel stems and fasteners to prevent corrosion from years of submerged service.
