Delta gate valves offer the ultimate in dependable service for stem, air, gas, oil vapor and high pressure installations. All have straight-through ports to assure minimum turbulence, erosion and resistance to flow. They are available in a wide variety of trims.

Standards:

 API 600

 API 598

 ABSU B16.34

 ANSI B16.10

 ANSI B16.5

 Standard material is ASTM A216 Grade WCB

 Standard trim is (13% Cr to hardface) which is suitable for a wide range of applications.

Delta Globe Valves are highly efficient for services requiring frequent operation and throttling when pressure drop across the valves is about 20% of inlet pressure. Closer throttling, creating higher pressure drops may cause cavitations or excessive velocities which could cause high noise levels, vibration and possible damage to the valve or adjacent piping. Globe valves can be equipped with optional operators and are available with a variety of trims to match service requirements.

Delta check valves are automatically actuated. They are opened and sustained in the open position by the force of velocity pressure and closed by the force of gravity. Seating load and resultant tightness is dependent upon back pressure.
