Giffco Valve is well known for their chemical feed equipment and specialty valves for pumps and other systems. From pressure relief, back pressure and injection valves to calibration columns, corporation stops and other chemical feed accessories, their high-quality products serve a number of industries.

A commitment to quality has always been at the heart of Griffco, and it starts with their professional team. Whether it’s the engineers designing the equipment, manufacturing personnel or customer service representatives, you can count on quality with Griffco. Since its inception, the company has produced more than a quarter million valves all over the world.

Most of the leading metering pump and many positive displacement pump manufacturers utilize Griffco valves in their systems. They know Griffco products are the best chemical feed components available on the market.


Griffco started in 1993 and has built a strong name for itself throughout the pump and pump accessory industry. Their home office is located in Amherst, New York and they are proud to manufacture all their products in the United States.


Water & Wastewater Treatment – Griffco valves and accessories are utilized in many water and wastewater treatment facilities all over the world. They are one of the only manufacturers who produce NSF certified valves and are ARRA compliant.

Power Generation Plants – Griffco is the preferred manufacturer for many of the OEM pump companies and their products are used in many power generation facilities.

Oil, Gas, Chemical & Petrochemical Processing – Griffco products are ideal in this industry because dealing with chemicals and petrochemicals requires such precise pumping procedures.

Pulp & Paper – Many pulp and paper mills count on Griffco as a leading supplier to enhance their pumps and chemical feed systems.

Other Markets – Griffco valves and accessories can be found in many different industries, such as mining, agriculture, food and beverage, pharmaceutical, bio-fuels, cooling towers and boilers, paints and coatings, plastics, resins, rubber goods and metals.


Without the right accessories, you may not get the proper performance from your pump. Griffco produces valves and other chemical feed accessories for specific applications in order to improve efficiency, accuracy, safety and longevity. Whatever your industry or pumping applications, Griffco offers the accessories you need for exceptional results.

Pressure Relief Valves (Safety or Bypass Valves)

When the pressure goes beyond a preset value, these pressure relief valves open to safely discharge the pressure into a separate reservoir. Griffco pressure relief valves are designed to protect your valuable capital equipment (pumps, systems and tanks) from wear and tear, or even worse, major breakdowns. They ensure all ancillary devices function properly. Griffco pressure relief valves are available in a wide range of sizes and flow rates. Custom-engineered valves can also be ordered per your specifications.

  • M Series for small connections
  • G-Series for Medium-to-large connections
  • High Flow for high-flow connections
  • High Pressure for high-pressure connections up to 2000 psi

Back Pressure Valves (Loading Valves)

When you need to stabilize downstream pressure from a pump, you need a back pressure valve to help maintain a consistent output rate. Minimum constant pressure is applied for stable operation and accurate flow rates on many reciprocating metering/closing pumps and other certain types of pumps. Griffco back pressure valves work with all major pump brands and custom solutions are available for specialty pumps.

  • M Series for low-flow applications
  • G-Series for Medium-to-large flow applications
  • High Flow for high-flow applications

Check Valves

By operating only in one direction, check valves are normally closed. Then, when the liquid passes through it, the valve automatically seals back up and prevents any reverse flow. Griffco check valves are manufactured with ball checks with high sphericity. This ensures a proper seal and no leakage.

Anti-Siphon Valves

With a different function than check valves, anti-siphon valves are designed to make sure liquids drain or empty by using the Venturi effect (siphoning). Suction is applied and the valve prevents liquid from flowing when upstream pressure stops.

Calibration Columns (Calibration Cylinders)

A calibration column is typically connected at the inlet of the pump. It contains a shutoff valve between the column and the tank, which provides isolation between elements in the system. Once the calibration column is full, the valve that leads to the tank is closed and then the pump can start drawing the fluid down. Griffco calibration columns are carefully engineered for high tolerances and precise graduations. This results in incredible accuracy. When it comes to calibration columns, Griffco offers more options and ranges than any other competitor.

Injection Valves (Injection Quills)

Injection valves and quills allow for the passage of liquid from a feed line into the center of a process line. However, an injection valve comes with an additional feature, which is the integral check valve. It keeps the liquids separated at the mating interface. Griffco makes superior injection valves that each come standard with integral check valves. Griffco injection valves are available in many different styles suitable for a variety of applications.

Corporation Stops

A corporation stop is similar to an injection valve, but it contains even more features. They include a shutoff valve and the injector can be removed without turning off the process flow. The quill can safely be removed once the shutoff valve is closed. Griffco corporation stops utilize all these components—and more—to produce exceptional results. They offer universal connection options along with inherent injection valve designs.

Gauge & Instrument Guards

Griffco manufactures instrument isolators and diaphragm gauges to improve the performance of chemical feed systems by protecting instruments from chemical attack.

Pulsation Dampeners

By reducing harmful shock waves and keeping the chemical dosage continuous, Griffco pulsation dampeners will help enhance your chemical feed system’s performance.


When you add a Y-Striner to the suction side of a chemical feed pump, it helps prevent debris from entering. This prevents clogging and potential damage to the inside of the pump head.
