Gate valves are characterized as having a rising or maybe a nonrising stem. Rising stems give you a visual indication of valve position. Nonrising stem valves will have a pointer threaded into the upper end with the stem to point out valve position. Nonrising stems are generally used underground or where vertical space is fixed.Gate valves are primarily intended for on-off services for gate valve. They are best found in ... Read more
Gate Valves offer an extended easy use in many industrial applications including oil&gas, chemical and petrochemical plants, thermal applications, fertilizer plants, etc… They function as on-off valves with bi-directional flow capacity and supplies an straight-through unobstructed bore at full open position. Therefore, your head loss in the valve is smaller than average provide a high flow rate capacity.
Rising stems are fixed to your gate and in addition they rise and minimize together because valve is operated, providing a visual indication with the valve position and making it possible to grease the stem gate valve. A nut rotates across the threaded stem and moves it. This type is suitable for above-ground installation.
Non-rising stems are threaded to the gate, and rotate with all the wedge rising and lowering in ... Read more

A nut rotates throughout the threaded stem and moves stainless steel ball valve . This type is simply suitable for above-ground installation.

Valve bodies are cast or forged to a variety of shapes. Although a sphere or possibly a cylinder would theoretically function as the most economical fit around resist fluid pressure every time a valve is open, there are various other considerations.For example, many valves call for a partition throughout the valve body to aid the seat opening forged steel check valve, which is the throttling orifice. With the valve closed, ... Read more
