GATE VALVES - Viadux

In metal seated gate valves, maximum torque on the spindle is associated with initial opening or cracking of the valve. Properly operated and closed, these valves can effect a drop tight seal but leakage rates of 2-10 ml/min are acceptable under AS 2638.1.

Gate Valve - an overview ScienceDirect Topics

Feb 01, 2019 · A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve. Gate Valve,gate valve with prices,brass gate valve,ValveGate valve Its closure principle is wedge seal face is consistent with the seat sealing surface and high gloss,fit each other.Which can prevent the medium from flowing and also to enhance the sealing effect rely on the backform,spring or the model of disc.

Pocketless smooth flow. Ease of operation. Negligible Head loss. Electrostatic powder coating / Liquid epoxy coating. Reference standard:BS EN 1171 / AWWA C-509. Viadux Valves - Valves - HDPE VIADUXGate valves are used to isolate sections of pipelines, branch off-takes and pieces of equipment. They are on-off valves designed for the primary function of flow isolation and should only be operated in the fully closed or fully open positions. The sliding motion of the gate is effected by a rotating screw, known as a spindle or stem.

Wedge Gate Valves

Ithuba Valves has manufactured and refurbished a number of gate valves for many water utility companies around South Africa including well-known such as Rand Water, Department of Water Affairs as well as mining industries and many more. The valves are of rising or non-rising spindle type depending on the customer or contractual requirements. All the manufacturing & refurbishments is done at our China Rising Spindle Gate Valve Suppliers, Manufacturers The gate of the wedge gate valve can be made into a whole, called the rigid gate; It can also be made into a gate that can produce trace deformation to improve its technology and make up for the deviation of the sealing surface Angle in the process of processing.
