Introduction
In industrial and commercial fire-protection networks, valves safeguard people, property, and critical processes by controlling the direction, pressure, and isolation of water flow. While ball valves excel at quick shut-off, gate valves offer full-bore isolation, and precision control valves fine-tune hydraulic balance, the humble check valve plays an equally decisive role: it prevents destructive backflow that can flood pump houses, trigger false alarms, and contaminate potable or process water supplies. In firefighting systems—where reliability during a genuine emergency matters more than in any other application—choosing a proven, code-listed swing check valve is a non-negotiable design decision.
The Tyco Fire Model CV-1F Grooved End Swing Check Valve meets that challenge head-on. Engineered for DN 50 – DN 300 (2″ – 12″) pipe sizes and rated to 300 psi (20.7 bar) working pressure, this compact unit combines rapid forward flow with dependable backflow prevention. Its robust ductile-iron body, stainless-steel hinge pin, and EPDM-faced bronze disc resist corrosion, erosion, and water hammer, while the integral grooved ends enable lightning-fast installation with industry-standard couplings. Certified by UL, C-UL, and FM, the valve delivers peace of mind to engineers, contractors, insurance auditors, and facility owners who refuse to compromise on fire safety.
Comprehensive Product Description
The Tyco CV-1F is a swing-type check valve: a clapper disc, hinged on a durable stainless-steel pin, swings freely out of the flow path when water moves in the forward direction. Should the flow cease—or, worse, attempt to reverse—the disc pivots back onto a resilient seat, sealing bubble-tight against a machined bronze ring. This simple, gravity-assisted mechanism has proven itself for more than a century, yet Tyco’s modern enhancements elevate performance to contemporary expectations.
Grooved End Convenience
By machining AWWA C-606-compatible grooves directly into the body, Tyco allows contractors to join the valve with two-bolt couplings in seconds—eliminating alignment headaches, hot-work permits, and the torque-wrench rituals associated with flanges. The result is faster installation, easier maintenance, and the flexibility to rotate or replace the valve without disturbing adjacent piping.
Compact, Flow-Friendly Body
Traditional swing check valves often suffer from bulky profiles and turbulent flow paths that waste energy. Tyco’s engineers refined the casting geometry to provide a smooth interior contour, minimising pressure drop even at the upper end of the 300 psi rating. In a world where pumps consume vast electrical power, every avoided foot of head results in measurable operating-cost savings.

Key Features and Benefits
Bubble-Tight Backflow Prevention
The EPDM-faced disc seals against the bronze seat ring with minimal seating force, guaranteeing no reverse leakage that could jeopardise system readiness or dilute foam concentrates in combined agent systems.
Low Maintenance Downtime
A single top cover secured by stainless-steel cap-screws permits rapid internal inspection. Technicians can replace the disc insert and gasket in minutes, returning the valve to duty without cutting pipe or draining the entire riser.
Energy-Efficient Hydraulics
A streamlined body cavity and thin, hydrodynamically profiled disc reduce turbulence, improving pump efficiency and sustaining sprinkler hydraulics—the lifeblood of any suppression network.
Corrosion-Resistant Build
Fusion-bonded epoxy inside and out shields the ductile-iron casting from raw-water corrosion, while bronze and stainless wetted parts shrug off micro-biologically influenced corrosion (MIC) that can plague lesser valves.
Universal Orientation
Unlike lift check valves, the swing mechanism operates reliably in horizontal mains or vertical risers (flow upward), offering layout flexibility for architects and BIM coordinators.
Grooved-End Versatility
The valve integrates seamlessly with steel, stainless, or ductile-iron pipe using rigid or flexible couplings—ideal for seismic zones or pump-house skid packages that demand vibration tolerance.
Industrial Applications
Fire Pump Discharge & Bypass Lines
After a diesel or electric fire pump stops, residual head can drive water backward into the pump casing, risking impeller spin in reverse. Installing the CV-1F immediately downstream prevents damaging reverse rotation.
Zone Isolation in High-Rise Buildings
Urban towers often employ pressure-reducing valves and staged zones. A swing check in each riser maintains unidirectional flow, protecting pressure regulators and preventing supply crossover.
Warehouse & Logistics Hubs
Long branch lines increase water-hammer risk when loads shift. The Tyco check valve’s smooth closure mitigates water hammer, reducing pipe-support fatigue and maintenance calls.
Data Centre Cooling Loops
Mission-critical facilities rely on dual-purpose mains for cooling and fire protection. Non-slam check performance ensures sudden chiller pump trips don’t back-feed fire-pump jockey circuits.
Petrochemical Process Water
In refineries, firefighting headers interconnect with process-water networks. The check valve isolates firefighting foam from contamination and meets FM Global insurance requirements.
