● Non-rotating stem with precision Acme threads and burnished finish. Valve suitable for horizontal installation.
● Universal trim. 13Cr stem, 13Cr faced disc, and alloy faced seats API Trim 8 suitable for service up to 850°F (454°C).
● Seat face alloy hard faced, ground, and lapped to a mirror finish. Conical seat machined to 8 RMS.
● Tapered disc.
Body guided disc accurately mates the hard faced surface of the disc with the surface of the seat, hard faced with 13Cr, alloy, SS 316, or Monel, ground and lapped with seat.
● Disc in SS 316 hard faced with 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.
Handwheel operated globe valve have backseat threaded in the bonnet, or for the pressure seal valves, welded to the bonnet. The hard facing is stellite 6 or equivalent.
The design of the body-bonnet gasket varies depending on the class of the globe valve.
Class 150 to 600 globe valves consist of a circular male-female connection with a graphite or spiral wound gasket.
Class 900 and above globe valves consist of a ring type joint.
In pressure seal designs the sealing in achieved through a gasket that takes advantage of the internal pressure of the line. The material most commonly used is high-purity graphite being located between the body and the body retainer ring.
Design Features
Design standard as per: BS1873、GB/T 12235
Generally, lift is just 1/4 of the valve seat port, ensuring a short Opening/closing time.
Only one sealing face exists on the valve body and disc.
The valve is designed as a back seat sealing structure.
Use flexible and woven graphite collaboration type packing.
