Product Brand: Sprague

Quality, high pressure products that provide that safety and control needed when integrating the Sprague high pressure pumps and boosters into complete systems.


We offer: Check Valves, Safety Relief Valves, Restrictor Valves, Gauge Savers, Gauges, Mufflers, and Filter-Regulator-Lubricator Assemblies.  Please click on the pages below for more information.

Check Valves

The high pressure check valves have a soft-seat poppet style design. All stainless contruction. Seal options, Buna, Viton, Neoprene, EPR

  • Pressures ranges: NPT to 10,000 psi, HPCT to 60,000 psi
  • Soft seat poppet type design ensures high reliability
  • Stainless steel components
  • Direct in-line mounting
Gauge Savers

Protect sensitive gauges, switches , other instruments and circuits against over-pressurization. It automatically closes when pressure exceeds pre-set level; automatically opens when circuit pressure drops below setting. Standard seals are Nitrile, optional seals available.

  • For hydraulic service only
  • Protects sensitive gauges, switches and other instruments against over-pressurization
  • Available in 5 ratios, with a pressure range 10 – 5000 psig
Safety Relief Valve

Suitable for line or panel mounting. Designed to operate at high pressures. Infinitely adjustable within pressure range. Body material stainless steel. Standard seals are Nitrile, optional seals available.

  • For hydraulic service only
  • Line or panel mounting
  • Adjustable ranges
  • Pressure range 200 – 20,000 psig
Restrictor Valve

An adjustable, flow-restricting valve for use in high pressure hydraulic applications.  Protects the discharge side of the pump from the damage caused by a sudden drop in pressure.  Ideal for HYDROSTATIC testing.

  • For hydraulic service only
  • Adjustable flow restricting valve
  • Prevents damage to system parts in  the event of a sudden drop in pressure
  • Used to reduce system pressure pulsation
  • Pressure range: NPT to 10,000 psi, HPCT to 30,000 psi
Gauges

Liquid filled gauges protect the internal components of the gauge preserving its integrity.  Selecting gauges that operate between 40-60% of the gauge range will provide excellent gauge life.

  • Pressures up to 60,000 psig
  • 4” diameter glycerin filled dial
  • Bottom connection
  • Stainless steel wetted parts
  • HPCT, NPT to 10,000 psi
Mufflers

Mufflers provide noise reduction on air-driven pumps and boosters.  Installing the properly sized muffler allows the system to exhaust the air-drive effectively with minimal restrictions and reduced potential for icing.

  • Reduces exhaust air noise
  • Used for system venting
  •  1/4", 1/2" ot 1 1/2" connection options
  • Stainless or nylon
Filter-Regulator-Lubricator Assemblies

Filter-Regulator-Lubricator conditions the air inlet to the air-driven pumps and boosters.

  • Delivers filtered lubricated compressed air at controlled pressure to operate cylinder, pump or air tools
  • Used in lubricated hydraulic pneumatic power units
  • assemblies, or separate components
  • Air gauge
