1、 Overview of ZKRR Electric O-Type Ball Valve

　　ZKRR electric O-type ball valveSuitable for situations where two are cut off or adjusted. The connection between the valve and the actuator adopts a direct connection method. The electric actuator has a built-in servo system and does not require a separate servo amplifier. It can control the operation by inputting a 4-20mA signal and a 220VAC power supply.ZKRQR电动O型三通球阀It has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action. The actuator can be configured with electronic electric actuators such as UNIC, PSQ, HQ, DHL, or pneumatic piston actuators such as GTX and AL according to user requirements.

3、 Characteristics of ZKRR electric O-type ball valve

1. The O-type fixed ball valve adopts a fixed ball design, with small opening and closing torque, flexible opening, and more stable operation.

2. The O-type fixed ball valve adopts a full pass design, which has the maximum flow capacity and negligible flow resistance.

3. The O-type fixed ball valve adopts a bi-directional stainless steel hard seal double seat structure, which has superior sealing performance, bi-directional sealing, strong shear force, and rated leakage flow coefficient.

4. The O-type fixed ball valve adopts a fixed ball design and adds a pre tension spring, making the ball valve have automatic pressure relief function.

5. The O-type fixed ball valve adopts a metal seat, which greatly improves the working temperature range.

6. The electric actuator adopts the latest electronic electric hospitality device, which has the advantages of compact structure, small size, reliability and durability.
