ZV200 Bypass Valve

The two-inch ZV200 is a low pressure build-up bypass valve designed for applications requiring protection for positive displacement pumps. Specifically designed for protecting pumps with capacities up to 250 gpm (946 L/min). The continuous internal bleed will assist in the operation of systems with "air" or "electric" operated internal valves. Typical applications include bobtail, transport and stationary loading and unloading of LPG, NH₃ and other light liquids.

Applications
Used for both truck and stationary applications for loading and unloading.

Notched cap over adjustment screw: Provides tamper-proof wiring feature to ensure the valve remains set by authorized personnel in the field. Square head adjustment screw: Allow for easy field adjustment. Multiple spring options: 41-70, 71-90, 91-125, and 126-150 psig different range. Corrosion resistant stainless steel internal valve: Increases durability and minimizes wear extending the life of the valve. Dual inlet and outlet gauge openings: Provide greater flexibility for mounting pressure gauges or a hydrostatic relief valve without adding a "Tee", "Weld-0-let" or special opening. Multiple flange options: 1.25", 1.5", 2", 2.5" NPT and weld flanges. No unions necessary for installation.

Features and Benefits
•	Dimensionally interchangeable with commonly used two-inch bypas valves; no need to change piping configuration.
•	Ductile iron construction offers maximum strength for higher pressures.
•	Flow rates up to 250 gpm (946 L/min) at 120 psi (8.3 bar) differential.
•	Continuous bleed helps equalize pressure to assist remote operated internal valves.
•	Multiple spring options enable you to select the pressure required for your truck or stationary application.
