CHECK VALVES

ElastoTITE™ Full Port Elastomer-Hinged Check Valves have low pressure loss, lightweight design and a compact construction. Patented Flexible Anti-Fatigue Reinforcement Layer design increases the life of the valve and reduces the need for replacement of the elastomer sealing member during routine maintenance. The elastomer hinge check valve design eliminates a restrictive valve seat and increases the valve’s open area and flow coefficient significantly.
ElastoTITE™ Check Valves - Male Thread End Series 801

The ElastoTITE™ Thread End Check Valve is perfect for compressed air and gas systems, water systems and vacuum pumps. Choice of body materials of Carbon Steel or 316 Stainless Steel. The available internals materials are Aluminum and 316 Stainless Steel. Buna-N is the standard seal with available optional seal materials of EPDM, Silicone or Viton.​

  • Materials can be configured to a Maximum Working Pressure of 150 PSI. Operating temperatures range from –40° F to 500° F with available sizes 1” thru 12” NPT

  • Patented Anti-Fatigue Reinforcement Layer – Our ElastoTITE™ Check Valve’s New Patented Anti-Fatigue Reinforcement Layer is substantially unstretchable and capable of resisting abrasion forces that are encountered while the valve is in operation, increasing the life of the valve significantly.

  • Smooth Valve Bore – The smooth machined bore allows the compliant valve seal to maintain a consistent check against backflow.

  • NPT (American National Standard Tapered Pipe Thread) Body – PDC’s Male Thread End Series 801 conforms to ASME/ANSI B1.20.1 American National Standard Tapered Pipe Threads on both ends of the valve.

  • NO Metal-to-Metal Rotating Parts – The motionless Hinge Bar and Seal Clamp design decreases wear of Hinges, Shafts, Valve Plates, and Springs slashing maintenance requirements and costs.

  • Full Port Seatless Design – Provides the largest flow area possible with the smallest pressure loss.

  • Fast Closure Feature – The closing time is reduced by the valve plate’s minimum travel from an open to a fully closed position.

  • Springless Design – Our valves operate without the assistance of a spring in the majority of all applications. With the assistance of a spring, the “slamming” action of the plates is all but eliminated. A spring is recommended when the valve is placed in a vertical downward flow pipeline position

  • Reinforced Valve Seal – Tolerant to liquids, gases, steam, chemical, oil, and fuel. The strength and durability of these elastomers ensure the prolonged life of the valves. The seals provide a tight shutoff.

  • Valves can be installed in a pipeline in any position.

  • Competitive Pricing – Competitive pricing, excellent customer service and quick turnaround to meet your needs.
