OEM Lug Type Butterfly Valve with Body Factory, Exporter
Product Description
General purpose lug butterfly valve manufactured according to EN 593. Wide range of standard materials available for various applications. The tongue and groove seat design locks the seat in place and gives the butterfly valve dead end capability.
Seat Test: Water tested at 1.1 times the working pressure to verify zero-leakage performance.
Functional/Operational Test: At final inspection, each valve and its actuator (flow lever/gear/pneumatic actuator) undergo a complete operational test (open/close). The test is performed without pressure and at ambient temperature. It ensures proper operation of the valve/actuator assembly, including accessories such as solenoid valves, limit switches, air filter regulators, and more.
The lug valve is mainly used for pipeline flow, pressure, and temperature control across industrial automation sectors, including electric power, petrochemical, metallurgy, environmental protection, energy management, and fire protection systems.
Offering responsive fluid control performance and effortless operation, these valves are broadly implemented in petroleum, gas, chemical, and water treatment operations, as well as critical cooling water systems in thermal power plants.

They are manufactured according to EN 593 standards, complying with international face-to-face dimensions such as API609, BS5155, DIN3202, and ISO5752.
Yes, the specialized tongue and groove seat design firmly locks the seat in place, giving the valve complete dead-end service capability.
The valves undergo a water seat test at 1.1 times the working pressure (110% rated pressure) to ensure tight bi-directional sealing and bubble-free closure.
Through the standard ISO 5211 upper flange, the valves can easily be fitted with manual hand levers, gearboxes, pneumatic actuators, or electric actuators.
It is primarily applied in petrochemical plants, thermal power station cooling systems, water treatment, fire protection, metallurgy, and automated fluid pipelines.
