Structural features and technical requirements of stem nut

The stem nut is sleeve parts, structural features and has general sleeve parts: main surface parts for

internal and external rotation surfaces require a higher degree of different axial parts; wall thickness of

thin easy deformation. And sleeve parts is different: the main stem nut rotation surface is trapezoidal

thread. This makes the general sleeve parts than processing more difficult.

The stem nut usually made of carbon steel or bronze, brass, nickel chromium iron ball. Low pressure

valve stem nut is also useful for nylon plastic. The stem nut is generally non ferrous metal casting blank;

carbon steel stem nut is larger for the forgings.

Stem nut main technical requirements are as follows:

1, trapezoidal thread and metric thread is generally 3 degree of accuracy, high pressure valve stem nut

for the accuracy of 2

2, the cylindrical surface for the 6 level accuracy

3, smooth surface and the outer cylindrical surface of the trapezoidal thread is at 5~ at 6

Our valve

We would like to introduce ourself as a professional valve manufacturer, especially in butterfly

valve(wafter type, lug type);check valve(wafer type dual plate, wafer type single disc, swing type... );ball

valve(flanged type, double-clip type, butt welded type, socket welded type& screwed end);Gate

Valve(API, MSS-70, DIN3352F4/F5&BS3464 standards);Resilient seal gate valve(DIN3352 F4/F5 Series).

Globe valve(DIN3202-F1, MSS-SP-85), Y Strainer(ANSI 125, DIN) and so on, Which are widely used in

oil, gas, water, power and steam station, transmission and distribution;Petrochemical, pulp and paper-

making, other industrial processes;and water, waste management. Meanwhile we also design some new-style valve in pipeline/water-treatment system
