D4 Valve with easy-Drive Actuator

November 2013

Description

TheD4controlvalvewitheasy-Driveelectricactuatorisacompact, rugged valve designed primarily for high-pressure

throttling applications. This valve is ideal for use on pressure and flow control applications within the oil and gas

production industry. The D4 valve also makes an excellent dump valve for high-pressure separators and scrubbers.

The D4 control valve meets the metallurgical requirements of NACE MR0175/ISO 15156 without environmental limits

for temperatures below 135_C(275_F). If the temperature is above 135_C (275_F), the N07718 Belleville washers will

impose some limits, as shown in table 3.

Specifications

Table 1 lists specifications for the D4 control valve with easy-Drive electric actuator. Some of the specifications for a

given control valve as it originally comes from the factory are stamped on a nameplate located on the lower actuator

enclosure.
