Design Standards and Design Features


The illustration of design features of cast steel globe valve

Design/Inspection standards: API 6D, API 600, ASME B16.34, BS EN13709, BS 1873, ASME B16.10, ASME B16.5.

 

(1) Handwheel operated with OS&Y and rising stem.

(2) Gland eyebolts are applied to facilitate packing maintenance and easy dismantling.

(3) Body/Bonnet joint design: male and female matching joint for 150LB~600LB; metallic ring gasket seal for 900LB and above.

(4) T-shaped anti blow-out stem design.

(5) Plug-shaped disc and seating face design allows particular flow characteristic.

(6) Seating surface shall be hardened by stellite 6 overlay.

Standards&Features:

Adoptive Standards

Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.
Seat Test: 1.1 times the working pressure with water.
Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
Special Test: On request, any other test can be carried out according to special instruction by client.

Product Advantage

1.The sealing surface has the advantages of good sealing performance, easy operation, no damage to the sealing surface, long service life and no water hammer phenomenon.
2.The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
3.Stem after the modulation and surface nit riding treatment, has a good corrosion resistance and abrasion resistance.
4.The product can be used with standard pipe flanges and flange sealing surface in the form, to meet the needs of various projects and user requirements.
