Q41F, Q41H/Y float type valve structure characteristics
1 the seat by the various advanced experience and design: the seat, to ensure that the valve seal, low friction torque, operating system. Many seat materials, wide application scope.
2 switch handle: the correct valve stem flat head, and handle the connection, thus ensuring the dislocation wont handle the switch state and valve instructions.

5. Antistatic properties: in the ball valve, the valve stem, between spring and can be set in the process of static switch is derived.
6 refractory structure parts: (ball valve body, flange, stem and body) designed to meet the fire resistance, metal contact with API607, requirements, API6FA.
