Gauge Guards Details
Gauge Guards

Plast-O-Matic gauge guards are utilized to isolate and protect pressure or vacuum instruments used on ultra-pure or highly corrosive fluid lines.

Gauge Guards

Gauge Guards barrier seal protects instruments from corrosion and clogging while maintaining high accuracy. Compact and ultra-pure zero dead leg designs available. They can be confidently used with liquids such as demineralized water, sulphuric acid, hydrochloric acid, and caustics. Use caution with chlorine applications and consult factory for recommendations. Utilization of Plast-O-Matic gauge guards offers the added advantage of protection against clogging of instruments caused by suspended solids or highly viscous fluids.

  • Highest pressure rating
  • Reduces instrument failures
  • No exposed top metal fasteners
  • Eliminates the expense and extended delivery of special alloy instruments

Solenoid Valves Details
Solenoid Valves

Electrically actuated valves for severe service applications for virtually all types of solutions. PTFE bellows barrier seal in both direct acting & pilot operated designs.

Solenoid Valves

The Plast-O-Matic Series EASMT solenoid valve is a single thermoplastic valve, designed for severe service applications with virtually every type of liquid. The EASMT Series is ideal for pressure, drain, or vacuum services. PTFE bellows design for pressure, drain, and vacuum service; for all types of aggressive chemicals, salt solutions, acids, caustics, and ultrapure liquids such as deionized water. Includes W24 fully rectified coil with Z-Cool DIN. Sizes from 1/4″ to 1″ in a wide range of materials and connection types.

  • Unique Design: PTFE Bellows barrier-type dynamic seal prevents leaking of fugitive emissions to the atmosphere
  • Versatility: For use with virtually every type solution, including acids, caustics, solvents, chlorine solutions and ultra-pure liquids
  • Dependability and Safety: Patented Fail Dry® design provides a visual warning if seal malfunctions. Avoids costly shutdown, as valve continues to function
  • Corrosion Resistant: Rugged thermoplastic construction is resistant to both internal and atmospheric corrosion. No metal parts in wetted areas

Pressure Regulators Details
Pressure Regulators

Accurately reduce and regulate steady or varying inlet pressures and maintain a constant, predetermined maximum outlet set pressure.

Pressure Regulators

Plast-O-Matic Pressure Regulators are designed to handle corrosive and ultra-pure liquids with inlet pressures up to 150 PSI at 75°F. Standard down-stream set pressure range is 5 to 125 PSI. The normally-open regulators incorporate a poppet seat at the valve orifice to prevent sticking and affecting the sensing of the downstream line pressure.

  • Protects sensitive downstream tools, instruments, tubing, and filters against damage from overpressure/pressure surges; permits the entire system to operate safely and effectively
  • Large surface area of its frictionless rolling diaphragm provides exceptional sensitivity
  • Double U-cups prevent leakage along the shaft and eliminates the possibilities of “creep”
  • Converts varying inlet pressure up to 150 PSI, to a stabilized, lower pre-set downstream

Check Valves Details
Check Valves

POM check valves prevent reverse flow of liquids. Designed with no wetted metals, they are ideal for use with water, extremely corrosive liquids, and ultra-pure liquids.

Check Valves

Series CKM A unique, patented diaphragm provides normally-closed operation with a bubble-tight seal, even with no reverse pressure. 1/2″ through 1″ pipe sizes. Series CKM & CK Check Valves, normally closed in design, feature a patented diaphragm seal that will neither stick nor chatter and is automatic in action. The valves are not dependent upon gravity so they can be mounted in any position.

  • Patented Design: Self-sealing – aren’t dependent upon gravity, mounting position or reverse flow, a significant improvement over ball check valves
  • Silent operation: No internal sliding or loose parts to slam or vibrate
  • Dependability: Leak-free sealing protects against the potential hazards created by reverse flow of corrosive liquids
  • Repeatability: Diaphragm automatically positions itself against seat in the identical location. Superior to ball check valves which often leak at lower pressures
