Figure : Flexible Wedge Gate Valve. The flexible wedge is a one-piece solid disk with a cut around the perimeter. 0000007724 00000 n Gate valves used in steam systems have flexible wedges. 0000004455 00000 n

0000015136 00000 n Product line: Pressure seal (forged and cast steel) valves. We're confident that we've been planning to possess a vibrant prospect and to be distributed all over the world within the years to come. Category: Gate, globe, and check valves The higher the body cavity pressure, the greater the force on the gasket in a pressure -seal valve.

ZECO wedge gate valve is one of the gate valve types. Body: ASTM A216 Gr.WCB, ASTM A352 LCB, LCC, A217WC9, C5, A351 CF8M,CF3, CF3M,CN7M, Disc: 13% Cr, 18%Cr8%Ni, Stellite, Monel Alloy20, Bronze, etc. For a rising stem valve, the stem will go up while opening the valve and move down when you close the valve. A cast-in recess or deeper and wider cut on wedge perimeter gives more flexibility but compromises the strength. What’s the Eccentric semi-ball valve used for? The valve disk is threaded internally. In inside screw design, the threaded portion of the stem is in contact with the flow medium, and when you open the valve, handwheel rise with the stem.

This means when a line is get heated by fluid and expand it does not create thermal blinding.

Combination Valve of butterfly Valve Check Valve Str... Resilient Seated non-rising Stem Gate Valve, WAFER TYPE BUTTERFLY VALVE-Flanged Type Butterfly Valve, CI,DI,Cast iron wafer type butterfly valve pn16. Gate valves should not be used for regulation or throttling of flow because accurate control is not possible. A gate valve is the most common type of valve used in any process plant.

0000013393 00000 n Wedge gate valve is generally used where need not strict requirements about size or harsh conditions such as high temperature and high pressure of the working medium or the closure of the need for long-term sealing. 0000001632 00000 n Flexible Wedge • Rising Stem. Velan stem seal offers tight seal with little to no maintenance over long periods of time. Thermal expansion of the steam line sometime causes distortion of valve bodies which may lead to thermal blinding.
