Product Description
15CV - 15000 Psi Single Ferrule Compression Check Valves
Hikelok O-Ring check valves with single-ferrule compression sleeve connection type. Provide unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure, valve shuts off. Hikelok Ball check valves prevent reverse flow where leak-tight shut-off is not mandatory. When differential drops below cracking pressure, valve closes.With all-metal components, valve can be used up to 650°F(343°C).
Features:
* Viton (FKM) O-ring: 0° to 400°F (-18° to 204°C)
* Buna-N O-ring: 0° to 250°F (-18° to 121°C))
* FFKM O-ring: 30° to 500°F (-18° to 260°C)
* PTFE O-ring: -100° to 400°F (-73° to 204°C)
* PTFE O-ring with Low Temp Spring: to -100°F (-73°C)
* Ball and poppet are an integral design to assure positive,in-line seating. Poppet is designed essentially for axial flow with minimum pressure drop
Advantages:
* Cracking Pressure: 20 psi (1.38 bar) ±30%. Springs for higher cracking pressures up to 100 psi available on special order for O-ring style check valves only
* Cracking Pressure: 20 psi (1.38 bar) +/- 30% Optional cracking pressures not available in Ball Style Check Valves
* Installation: Vertical or Horizontal as required. Flow Direction Arrow marked on valve body.
More options:
* Optional Monel, Inconel 600, Titanium Grade 2, Hastelloy C276, Inconel 625, and Incoloy 825
* Optional ball type check valves
20CV - 20000 Psi Medium Pressure O-ring Check Valves
Hikelok Medium Pressure Check Valves, nicknamed are designed for use with 20 Series valves and Hikelok Medium Pressure tubing. They incorporate conedand-threaded connections with the orifice sized to match the high-flow 15,000 psi tubing options shown later in this brochure. For instructions on how to make this Medium Pressure Cone & Thread connection and the tools necessary to accomplish.
Features:
* Utilize High Flow Medium Pressure Coned-and-Threaded connections
* Tubing sizes available from 1/4" to 1"
* Working temperature from 0°F to 400°F (-17.8°C to 204°C)
* PMaximum working pressure up to 20,000 psig (1379 bar)
More options:
* Optional O-Ring and ball type
* Optional wetted materials of cover gland and ball poppet for longer life
* Optional special materials available when corrosion, temperature, or NACE/ISO 15156 requirements demandOptional wetted materials of cover gland and ball poppet for longer life
Features Advantages:
* Prevents reverse flow where leak-tight shut-off is not mandatory (Not for use as relief valve)
* Cracking pressure: 14 psig~26 psig (0.966 bar~1.794 bar)
* Provides unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure, valve shuts off (Not for use as relief valve)
* Resilient O-ring seat design for noise-free closing and zero leakage
* An integral design of the ball and poppet to assure positive, in-line seating without "chatter".Poppet is designed essentially for axial flow with minimum pressure drop.
60CV - 60000 Psi Medium Pressure O-ring Check Valves
Hikelok High Pressure Check valves provides unidirectional flow and tight shut-off for liquids and gas with high reliability. When differential drops below cracking pressure, valve shuts off.
Features:
