Siemens 256-02011 Globe Valve Assembly 10-15 psi (1/2 in)

Product Description

The Siemens 256-02011 is a 2-way globe valve assembly with a 1/2 in. brass valve body and a pneumatic actuator. It has a flow coefficient (Cv) of 4, a 7/32 in. actuator stroke and a 1/8 in. NPT barbed air connection, and operates with a 10–15 psi actuator pressure range. The valve is normally closed and rated for water and water-glycol solutions to 50% at 35°F to 250°F.

• 2-way, 1/2 in. brass globe valve; flow coefficient Cv = 4; normally closed
• Pneumatic actuator with 7/32 in. stroke, 2 in. actuator size, 10–15 psi spring/pressure range and 1/8 in. NPT barbed air connection
• Service for water and water-glycol up to 50%; close-off pressure 50 psi; operating temperature 35°F to 250°F; modified equal percentage flow characteristic
