Home » Products » Globe Valve

Globe valves is very suitable for control the medium, because of this type of valve's stem opening or closing at a short trip, and it has very reliable breaker function. Therefore, this type of valve is suitable for cutting, adjusting and throttling the medium.

Dawei manufactures Globe Valves that are primarily used to stop, start and regulate fluid flow in pipelines. Globe Valves can shut off fluid flows by moving the disc against the flow stream. These valves are particularly common in on-off services, but can be used for various applications.

Dawei manufactures globe valves in a variety of materials, including iron, stainless steel, cast steel and bronze. Styles include corrosion resistant, pressure seal and cryogenic globe valves. For questions about our Globe Valve offerings and their capabilities, please contact Dawei today!

Features and Benefits

Non-rotating stem with precision Acme threads and burnished finish. Valve suitable for horizontal installation.

Universal trim. 13Cr stem, 13Cr faced disc, and CoCr alloy faced seats API Trim 8 suitable for service up to 850°F (454°C).

Seat face CoCr alloy hardfaced, ground, and lapped to a mirror finish. Conical seat machined to 8 RMS.

Tapered disc.

Body guided disc accurately mates the hardfaced surface of the disc with the surface of the seat, hardfaced with 13Cr, CoCr alloy, SS 316, or Monel, ground and lapped with seat.

Disc in SS 316 hardfaced with CoCr alloy also available. NPS 2–6 (DN 50–150) valves may have solid CA15 (13Cr) discs.

Body and bonnet. Castings are precision machined. One-piece bonnet for better alignment, fewer parts.

Stuffing box finish to 63 RMS or better.

Body and bonnet joint accurately machined. Fully enclosed gasket.

Gland has two-piece construction for easy alignment.

Rotating stem nut. Austenitic ductile iron Gr. D-2C, renewable in-line.

Torque arm reduces wear on packing rings and enables better sealing and reduces torque.

Impactor handwheels.

Globe and stop check valves require higher closing torques than gate valves with the same seat diameter and pressure class. The most economical mechanism for tight shutoff is the impactor handwheel. Two lugs cast under the wheel strike simultaneous blows and give 3–10 times the closing force of standard handwheels. Impactor handwheels are supplied at manufacturer's option unless specified by customer.
