Leslie Control Valves for Gtw Three Way Control Valves
The Three Way Globe Valve design has been successfully applied for over 50 years in chemical, refining, power, paper, and H.V.A.C. industries worldwide. They are designed for mixing or diverting of clean, dirty, viscous and corrosive liquids, high and low pressure steam, and clean, dirty and corrosive gases.
MIXING SERVICE (Type MX)
The inner valves in type MX seat inside the two seat rings. When these valves are used for mixing service, the forces developed by the two inlet flows oppose each other, creating little, if any, unbalance. Thus, the actuator can control the flow efficiently, with very little power lost in overcoming dynamic unbalance.
The type MX valve is also used for diverting service, generally restricted to the smaller sizes.
DIVERTING SERVICE (Type DV)
In contrast to the MX control valve, the inner valve in the type DV seats outside the twoseat rings. The flow enters between the two seats and the pressure tends to move the inner valve away from the seats, adding to the stability of operation. Therefore, the Type DV is preferred for diverting service in larger valve sizes and at higher pressure.
All Leslie Control valves are 100% factory tested and serialized. Leslie Controls’ quality assurance program is accredited and certified to ISO 9001 .
