Griffco G-Series diaphragm back pressure valves with solid PTFE flanges are designed to enhance the performance of chemical feed systems by applying a continuous back pressure to the chemical feed pump, while also acting as an anti-syphon valve. Robust construction ensures reliability in the rigorous service of municipal and industrial applications.
This compact and economical valve performs four important functions for your LMI pump
Griffco G-Series diaphragm pressure relief valves with solid PTFE flanges are designed to protect chemical feed systems from over pressure damage caused by defective equipment, a blockage in the chemical feed line, or a shut valve. Robust construction ensures reliability in the rigorous service of municipal and industrial applications.
Griffco PVC and Borosilicate Glass calibration cylinders are designed to enhance the performance of a chemical feed system by providing a verification of the flow rate of the chemical feed pump. Griffco offers a wide range of calibration column sizes and material options that work in many different applications.
Griffco's new Unibody back pressure valve is the latest innovation to ensure leak-free connections and operation.
LMI's diaphragm back pressure/anti-syphon valves apply positive discharge pressure to a metering pump system and act to stabilize the output of higher output LMI Metering Pumps when pumping into low or no-pressure systems.
Hayward Butterfly Valves are used for throttling or quick quarter-turn on-off control.
Hayward’s DAB Series industrial all-plastic diaphragm valves are engineered to provide superior handling of difficult media such as corrosive fluids, abrasives and slurries. They can also be used for high purity and sanitary applications.
The Hayward EJM Series reversing electric actuators are cost effective, rugged, quarter-turn actuator designed for use with all ball and butterfly valves up to 24" in size.
The Hayward EVR Series reversing electric actuators are economical, high performance actuator for use with all true union ball valves, three-way ball valves, and butterfly valves up to 4" in size.
The Hayward Needle Valves are used for accurate metering of fluids. Turning the thumb-wheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute. Precision-molded, fine-pitched stem threads permit this very fine metering flow control.
The Hayward PAD Series pneumatic actuators are corrosion-resistant air-to-air (double acting) quarter-turn actuator for use with ball valves up to 2" in size.
The Hayward Pressure Regulators prevent downstream pressure from exceeding a preset pressure. When the upstream pressure increases beyond the set pressure of the regulator, the regulator prevents the downstream pressure from exceeding the set pressure.
The Hayward Pressure Relief Valves protect piping system components from damage due to over pressurization.
Hayward’s Spring Loaded Y Check valves give positive protection against reversal of flow in a piping system – even in the absence of backpressure.
The Hayward all-plastic swing check valves have up to twice the temperature/pressure rating of other plastic swing check valves...and can often replace metal valves in many applications.
The Hayward true union ball valves are constructed of rugged, heavy wall plastic and stands up to the most aggressive of applications.
The Hayward Manual Three-Way Ball Valves come standard with a two port “TW” ball allowing for three flow configurations within 180° of rotation. Hayward all-plastic Three-Way Valves contain no metal parts.
The Hayward Y Check Valves prevents reversal of flow in piping systems. They are ideal where back flow could potentially cause damage to pumps, filters or process equipment.
Sigmamotor back pressure valves prevent siphoning and varying rates of dosage from fluctuating downstream pressure by enacting positive discharge pressure in your metering pump system.
Sigmamotor pressure relief valves operate when the system pressure raises above the set pressure of the valve to protect systems from damage due to blockages or excessive pressure situations.
Provide back pressure and anti-syphon protection in addition to standard venting functions.
