ZV200 Bypass Valves

ZV200 Bypass valve 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.

The two-inch valve 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).

As part of Corken’s continuous improvement program, repair kits with Buna-N trim are now available for each bypass valve. For a complete parts list and instructions for disassembly and assembly, consult the respective Installation, Operation, & Maintenance (IOM) manual.

Applications

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

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.
