    full bore brass water ball valve 1/2"-2"

    The specification of full bore brass water ball valve 1/2"-2"
    *Electric Butterfly Ball Valve
    *Non-intrusive design IP67
    *Torque:50~1600Nm
    *1/3 size & weight

    full bore brass water ball valve 1/2"-2"

    I. Product Overview

    lZdapan products and performance is world advanced level intelligent non-intrusive electric actuators which can be commissioned without removing covers. Users only need to setup once at both FULLY OPEN and FULLY CLOSE positions if there is no special requirement.

    lThe product is composed of embedded electromotor, gearbox, control box integration, manual handle, local digital display, local operation buttons etc.


    l Small size and light weight. (1/3 of comparable products) It is especially suitable for small size ball valves and butterfly valves in limited, frequent vibrating space.


    l Zdapan Valve has wide range of product line: we offer On-Off duty, pulse control and modulating duty..


    lPower supply: single phase 220V/AC, 3-phase 380V/AC, other power supply is also provided under request.


    lTorque range: 50Nm~2000Nm


    lProtection Level: IP67 EX level: dIIBT4

    II. Main Features

    lElectrical control box is double-sealed enclosure largely increase the reliability and service life by avoiding damages to the circuit board if the control box is uncovered or water leaking into wiring holes.

    lWe adopted digital tubes and display valve position, malfunction and alarm info directly from the machine.

    l The box that carrying loads is made of cast iron and it increases its durability. Load capacity is approximately 2 times of comparable products.

    l Worms are immersed in a inclosed liquid oil so that life is 3 times of comparable products.

    lWe adopt professional lightening-proof technology.

    lElectrics double protection: The peripheral protection circuit shut off the main power when main control weak current system is malfunctioned. Therefore, it avoids damages to the actuators and the valves.

    lWe avoid the trouble of battery lose no matter if the power is on by removing battery in actuators; therefore, completely avoid the setup change due to manual operation under power outrage.

    lLocation sensor is made of conductive plastic potentiometer used in space technology which ensure long service life and high reliability.

    full bore brass water ball valve 1/2"-2"

    A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restric­tion is desired. The gate faces can form a wedge shape or they can be parallel. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed.

    OFFSET1 The shaft is offset behind the seat axis to allow complete sealing contact around the entire seat

    OFFSET2 The shaft centerline is offset from the pipe and valve which provides interference free opening and closing of the valve

    OFFSET3 The seat come axis is offset from the shaft centerline to eliminate friction during closing and opening and to achieve uniform compressive sealing arount the entire seat.

    (1)Seat is Cr13 matal alloy or hardfaced with Stellite as standard.

    (2)The gasket is spiral wound SS/Graphite for zero leakage.

    (3)Seat ring forces are generated by the torque during closing uniformly around the entire circumference.The resilent seal fleses and energizes,assuming the shape of the seat,The compression forces equally distributed around the perimeter provide a tight bi-directional shut off. The resiliency of the seal allows the valve body and disc to contract or expand,without the risk of jamming duo to temperature flunctuations.It is self-adjusting.
