Griffco Valve

Griffco accessories help stabilize metering pump operation, reduce process variability, and protect system components.

Common Griffco chemical feed accessories include:

• Back pressure valves
• Pressure relief valves
• Calibration columns
• Chemical injection valves and injection quills
• Pulsation dampeners
• Fusion dampeners
• Y-strainers
• Corporation stops
• Gauge guards
• Inlet stabilizers
• Pump accessory assemblies

Back-pressure valves apply continuous pressure to chemical feed pumps. Pressure relief valves protect the pump and system from over-pressurization, blocked discharge lines, and closed valves.

Back Pressure Valves for Metering Pump Stability

Back-pressure valves stabilize downstream pressure, allowing reciprocating metering and dosing pumps to maintain consistent discharge flow. This supports proper check valve seating, reduces the risk of siphoning, and improves dosing repeatability.

Griffco back-pressure valves are commonly used when a pump discharges into a low-pressure line, variable process conditions, or changing head height. IPE helps customers evaluate back pressure requirements based on pump type, discharge pressure, chemical characteristics, and process conditions.

Pressure Relief Valves for Pump and System Protection

Pressure relief valves protect chemical feed systems from pressure spikes and blocked discharge conditions. When pressure exceeds the set point, the valve opens to bypass fluid and protects the pump, piping, tubing, fittings, and downstream equipment.

In chemical dosing applications, relief valve design must account for pump capacity, chemical compatibility, system pressure, relief path, and safe chemical return or containment. IPE helps customers select pressure relief configurations for water treatment, wastewater, chemical processing, agricultural fertigation, and utility systems.

Calibration Columns for Dosing Verification

Calibration columns allow operators to verify pump output by measuring chemical drawdown over a set period. This helps confirm the flow rate, identify changes in pump performance, and maintain accurate chemical feed control.

Griffco calibration columns are used for field calibration, startup verification, troubleshooting, and routine maintenance. IPE can help integrate calibration columns into new or existing chemical feed systems for easier testing and performance checks.

Pulsation Dampeners for Smoother Chemical Feed

Positive displacement metering pumps can create pulsation in the discharge line. Excessive pulsation can cause pressure fluctuations, vibration, inconsistent injection, stress on fittings, and premature component wear.

Griffco pulsation dampeners reduce shock waves and help deliver a more continuous chemical dose at the injection point. Griffco offers plastic and metal dampeners in different pressures, materials, and connection sizes.

IPE helps customers evaluate pulsation control based on pump style, stroke speed, discharge pressure, line length, fluid characteristics, and injection point requirements.

Injection Valves and Quills for Controlled Chemical Delivery

Chemical injection point design affects mixing, treatment performance, pipe protection, and maintenance access. Griffco injection valves and injection quills introduce chemicals into the process stream while helping separate the feed line from the process fluid.

Injection valves may include an integral check valve to help prevent backflow into the chemical feed line. Griffco also offers serviceable injection valve and quill designs for cleaning and inspection.

IPE helps customers evaluate injection requirements based on chemical type, pipe size, process flow, pressure, compatibility, and desired mixing behavior.

Y-Strainers and Suction-Side Protection

Chemical feed pumps are sensitive to debris, crystallized product, and solids that can affect check valves, pump heads, seals, and tubing. Griffco Y-strainers help protect the suction side of chemical feed systems by reducing debris entering the pump.

IPE helps customers evaluate suction piping, strainer placement, chemical characteristics, and maintenance access so accessory selection fits the full system design.
