Products
As the performance leader in the development of plastic valves and controls, Plast-O-Matic provides a complete line of standard and custom designed solutions for difficult applications. The corrosive liquid markets use Plast-O-Matic products for the control of sodium hypochlorite, nitric acid, hydrochloric acid, phosphoric acid, sulfuric acid, solvents, chlorine, hydrogen peroxide, ethylene glycol, seawater, detergents, surfactants, brine, oil, fluoride, ferric chloride, sodium bi-sulfate, ferric sulfate, and calcium chloride.
See Product Diagram Below.
-
Ball Valves
Actuated & Manual Ball Valves feature trunnion safety design and dual sliding seats for ultra-smooth operation and repeatable bubble-tight shutoff with an incredibly long cycle life. Available 2-way and 3-way, in 3/8"– 4" sizes.
See Product Diagram Below.
-
Check Valves
Leak-proof check valves prevent reverse flow of water, extremely corrosive, and ultra-pure liquids. A unique, patented diaphragm provides normally-closed operation with a bubble-tight seal, even with no reverse pressure. An encapsulated spring and sliding poppet recreates this performance in larger sizes. ½" through 4" sizes.
See Product Diagram Below.
-
Gauge Guards & Instrumentation
Choice of PTFE or Viton barrier seal protects instruments from corrosion and clogging while maintaining high accuracy. Compact and ultra-pure zero dead leg designs available. Flow, level, and pressure switches signal equipment as system parameters change. Differential pressure gauges, variable area flow meters and fluid presence sensors indicate system changes at a glance. Plast-O-Matic instruments are designed with isolated or coated metals to prevent corrosion and process contamination.
See Product Diagram Below.
-
Pressure Regulators
Accurately reduce and regulate steady or varying inlet pressures and maintain a constant, predetermined maximum outlet set pressure. Offered in spring controlled, air controlled, differential controlled and ultra-pure designs, Plast-O-Matic regulators are consistently recognized as the industry’s top performers for maximum flow with minimal drop-off from set pressure. ½" through 4" sizes.
See Product Diagram Below.
-
Relief, Backpressure, Bypass & Anti-Siphon Valves
Prevent system overpressure, regulate backpressure, provide automatic bypass, and eliminate siphon with high performance relief valves. 2-way and 3-way designs, straight and angle pattern, choice of elastomer or PTFE diaphragm design. ¼" – 3" sizes.
See Product Diagram Below.
-
Shut-off & Diverter Valves
Variety of air operated, line pressure assisted, and manually operated shut-off valves in both diaphragm and globe styles. Air operated pinch valves, quick dump valves, and three-way valves also provide bubble-tight shut-off for a variety of applications. Available in compact and heavy duty designs with a number of options including fail-safe spring return, limit stops, visual indicator windows, and the patented Fail-Dry® early warning vent.
See Product Diagram Below.
-
Sight Glass & Level Indicators
For safe, positive indication of flow and clarity of corrosive or ultra-pure liquids. Single-wall design for liquids compatible with acrylic; double-wall design features Pyrex inner cylinder for all other applications. Optional streamers provide instant visual proof of flow. ½" to 8" sizes.
See Product Diagram Below.
-
Solenoid Valves
Electrically actuated valves for severe service applications for virtually all types of solutions. PTFE bellows barrier seal in both direct acting and pilot operated designs; proven million-cycle life provides lowest cost of lifetime ownership. Normally-open and three-way models available. ¼" through 3" sizes.
See Product Diagram Below.
-
Venting Valves & Vacuum Breakers
Air release valves provide high capacity venting of gas at system start up, while degassing valves vent trace amounts of gas as it occurs during system operation. Vacuum breakers open automatically in response to minimal vacuum to prevent unwanted siphonage or collapse of storage tanks. Plast-O-Matic degassing vent & vacuum breaker valves automatically seal bubble tight when not in use; air release valves automatically reseal when liquid fills the valve.
See Product Diagram Below.
-
Miscellaneous Process Control & Pumps
- Constant Flow Valves provide pre-set constant downstream flow rate.
- Air Operated Filling/Metering Pumps for precise filling, dosing, dispensing of ultra-pure liquids and corrosive chemicals.
- Process Cooling Sticks supply or return side assemblies simplify piping and provide superior strength.
- Pulsation Dampeners/Surge Suppressors water hammer arrest and pump pulsation dampeners improve performance and safeguard against system damage.
See Product Diagram Below.

PLAST-O-MATIC HAS 50 YEARS OF EXPERIENCE in the control of ultra-pure liquids. The high purity and ultra-pure liquid markets use Plast-O-Matic products for the control of deionized water, reverse osmosis water, ultra-pure chemicals, sanitary process liquids, and sodium bicarbonate. Our proprietary two-part preliminary cleaning procedure is key to our high purity products. First, surfaces are treated to be amenable to the scavenging of metallic residues, mold release agents and ancillary contaminants. SEMI F-57 compatible agents are used to scour the activated surface.
See Product Diagram Below.
-
High Purity Pressure Regulators
Ultimate combination of flow performance and purity; features machined Kynar 740 body with metal ion-free EPDM elastomer and non-rising adjustment. Includes choice of spigot types and proprietary POM pre-assembly cleaning, 8 hour cold/hot rinse, and final Class 100 clean and double-bag procedure. Design also closes bubble tight in the event of severe overpressure.
See Product Diagram Below.
-
Ultra-Pure Pressure Regulators
Cleanest pressure regulator on the market features convoluted TFM diaphragm and no external fasteners and is designed to meet SEMI F-57 specifications. Includes choice of spigot types and proprietary POM pre-assembly cleaning, 8 hour cold/hot rinse, and final Class 100 clean and double-bag procedure. Non-closing design for continuous flow systems.
See Product Diagram Below.
-
Zero Deadleg Instrument Isolators
Unique in-line design eliminates dead leg that can harbor bacterial growth and contamination. Unpigmented thermoplastic material. Special flexible elastomer spool separates system liquid from gauge fill liquid and assures accurate reading; choice of FKM or metal ion-free EPDM. Choice of spigot types; available with or without gauge.
See Product Diagram Below.
-
Quick Dump Valves
Drain mounted for rapid vortex emptying of a sink or tank. IDA is available as double-acting air by air or normally-closed spring return design. High capacity design provides up to twice the flow rate of typical dump valves; remains bubble-tight with up to 25" of head.
See Product Diagram Below.
-
Diaphragm Valves
Long cycle life and compact design: Air to open/spring return normally closed. Excellent for delivering water, ultra-high purity or highly corrosive liquids to spray heads and other points of use. PTFE diaphragm with no wetted elastomers plus smooth internal cavities preserve purity and avoid deadleg. Connections can be female socket, female threads, spigots, or flare.
See Product Diagram Below.
-
Backpressure Valves
PTFE diaphragm provides the ultimate in corrosion resistance and contamination free sealing with no wetted elastomers. Versatile valve functions as backpressure regulator, pump backpressure, bypass, relief, or anti-siphon valve. For water, highly aggressive and ultra-pure liquid applications.
See Product Diagram Below.
-
Lateral Reducing Valves
Revolutionary ball valve adapter eliminates weakness inherent to lateral drops; installs easily into the tee without additional fittings. Also an ideal replacement for costly zero dead-leg valves.
See Product Diagram Below.
-
Process Cooling Sticks
Rugged, reinforced assemblies for process cooling water applications combine valves, gauges, flow meters and connectors into compact “sticks” that are virtually indestructible and drastically reduce installation costs. PCWS supply side features pressure regulator and pressure gauge; PCWR return side features flowmeter and throttling valve. Customizable with any combination of valves and connections. Eliminates poor flow performance and rouging inherent with stainless steel products.
