Spring is completely removed from fl ow pathClosedAs the inlet supply pressure decreases, a light spring closes the poppet, positioning the knife-edge automatically in line of contact sealing against the o-ring. The impression of the knife edge is limited by a metal-to-metal seat, which carries the reverse pressure load and serves to prevent sticking of the o-ring.Features & Benefi tsLow pressure• Lightweight check valve for pressures to 25 psig.Ultra-sensitive• Unique design allows fl ow with minimum pressure diff erential. Cracking pressure is 4? H2O maximum.Positive sealing• Unique knife-edge on the poppet positions snugly to provide zero sealing even with extremely low pressure.Zero leakage• Compact, easy installation. Effi cient, inline design reduces size and weight. The valve can be mounted in any position.Technical DataBody Construction Materials Aluminum, brass, steel, 303 or 316 stainless steelO-ring Materials Buna N or Viton®Operating Pressure 25 psig (1.7 bar)Cracking Pressure 4?

A repair kit may be ordered by placing a ‘K/’ in front of the complete part number (i.e. K/119B–2PP).Although we off er separate kits where o-ring replacement is considered necessary, factory repair is recommended. Because of the ultra-sensitive characteristics of this valve, extreme care is necessary to insure that the o-ring is properly fi tted into the groove without being twisted or distorted.For Your SafetyIt is solely the responsibility of the system designer and user to select products suitable for their specifi c application requirements and to ensure proper installation, operation, and maintenance of these products. Material compatibility, product ratings and application details should be considered in the selection.

When ordering a cracking pressure within the standard range or below the standard range of the cracking pressure, the dash number is a “maximum”. Example: 259A–4TT–.3 (cracking pressure tolerance will be +0%, -50%). When ordering a cracking pressure equal to or greater than the upper limit of the standard cracking pressure shown above, cracking pressure tolerance will be ±10%. Example: 259A–4TT–5. Cracking pressure over 8 psig should not be specifi ed without consulting the factory. Where 200 Series valves are supplied with higher cracking pressures, a shroud ring may be used to confi ne the o-ring.Note: Reseat pressure is the back pressure required to seal a check valve. It varies with diff erent springs and seals. Reseat pressure is not specifi ed unless called out on the sales order.LeakageExternal: ZeroInternal:Elastomeric seals: ZeroPTFE seals: 0–50 psig = 5cc/min max. 50+ psig = 0.5cc/min max.Operating Pressure: 200 SeriesAluminum (A) Tube 3/16?–1½? 0–3000 psig to 200° FPipe 1/8?–1½? 0–3000 psig to 200° FBrassTube 3/16?–1½? 0–3000 psig to 300° FPipe 1/8?–1½? 0–3000 psig to 300° FPipe 2? 0–1500 psig to 300° FSteel Tube 3/16?–1½? 0–3000 psig to 300° FPipe 1/8?–2? 0–3000 psig to 300° FStainless steel Tube 3/16?–1½? 0–3000 psig to 450° FPipe 1/8?–2? 0–3000 psig to 450° FOperating Pressure: H200 SeriesAluminum (A) Tube 3/16?–1¼? 0–6000 psig to 200° FPipe 1/8?–1½? 0–6000 psig to 200° FBrass Tube 3/16?–1¼? 0–5000 psig to 300° FPipe 1/8?–1½? 0–5000 psig to 300° FSteel Tube 3/16?–1¼? 0–5000 psig to 300° FPipe 1/8?–2? 0–5000 psig to 300° FStainless steel Tube 3/16?–2? 0–6000 psig to 450° FPipe 1/8?–2? 0–6000 psig to 450° FOptional(Based on availability)Circle Seal Controls Check Valves5200 Series / H200 SeriesEnd ConnectionAlum.

PTFE used in seats and poppets is self-lubricating and resistant to corrosion.• Noise Free Chatter due to pulsation in the fl uid system is absorbed by the resilient materials and unique design of the seat and poppet.• Adaptable to Most Fluids Standard bronze,brass, steel, and stainless steel valves with PTFE seats and poppets are suitable for a wide range of fl uids. Valves with bodies of PTFE are BIVCO specialties for corrosive fl uids.BIVCO valves are considered all-purpose valves because they can be tailored in the right combination of materials for the job at hand…for liquids, including acids, alkalais, formaldehyde, solvents, oils, gasoline, water, sea water, deionized water, pharmaceutical liquids, steam condensates, refrigerants…for gases including air, oxygen, argon, helium, nitrogen, dry chlorine, sulphur dioxide…for vapors including saturated steam, wet chlorine, and various others.How it WorksThe BIVCO Floating Seat and PoppetThe operating principles of BIVCO valves are unique. The conical seat of PTFE or other high performance plastic fi ts loosely when snapped in place and then becomes free fl oating, permitting horizontal, vertical and radial movement. In the closed position, the wedge-like action of the conical poppet seals the seat against the body, assuring positive, bubble-tight sealing. In the open position, the seat again becomes free fl oating.Poppet making contact with seat Poppet in closed positionOperating CharacteristicsCircle Seal Controls2301 Wardlow Circle • Corona, CA 92880Phone (951) 270-6200 • Fax (951) 270-6201www.circlesealcontrols.com24BIVCO Check ValvesDescriptionBIVCO 1000 Series are highly reliable lift type models which provide positive, zero leakage sealing and low-pressure drop.
