It is strongly recommended to replace the valve seat and valve cover gasket with spare parts kit. Assemble in the reverse order of disassembly. Use the specified torque to tighten the flange connecting bolts crosswise. Tighten the stem nut with the specified torque.
A floating ball valve is a ball valve with an unsupported ball — other than the two seats it rests on — so that the ball moves in the valve cavity to help seal off the line pressure. The key to ball valve performance is the sealing design, regardless of whether the seats are made of metal, plastic or other material.
The ball valve may have an internal leakage during use or installation. Due to the frequent switch in use, or failure to install as required, the ball valve may not work properly. In the following part, Xhvalve will explain the reasons and solutions for the leakage of the ball valve. 1. Causes of ball valve internal leakage
Ball valves sealing tightly on both seats can trap chlorine in the body cavity when closed. Dangerous pressures can build if temperature rises, unless means are provided to safely relieve this pressure. The Chlorine Institute recommends two ways to do this: 1. Self-relieving seats – The downstream seat seals, and the upstream
KLINGER ® ball valves - Ballostar, Monoball & Monolith Range. Ball valves, due to their main characteristics, are highly versatile in terms of fluid handling and among the most popular valves found in the industry. Ball valves feature a quick closing ¼ turn, which is usually achieved by means of a lever, thus allowing for simple operation.
Boiler drain valves eliminate water from a boiler and also release any sediment that may have accumulated within the heating system. These can also be used as a general-purpose hose end valve for external water service. An all-or-nothing valve that completely shuts off the flow of a liquid, ball valves are the most common type of residential valve.
The BV, SBV, SBV-P, and BVS valves have replaceable stem orings as well. If the valve leaks past the ball then the seats may have become permanently damaged in which case the valve either needs to be replaced or in the case of the BV, SBV, SBV-P, …
Ball Valve Seats. Seats and inserts, which are important components in the valve industry, as a critical component, PTFE is very often to choose as the raw material. PTFE provides a low friction seat, with excellent media compatibility. Filled grades provide wear resistance and can support seating loads of the higher class of valves.
The upfront purchase price of a metal seated ball valve is definitely more than a soft seated ball valve. However, one should consider the cost of downtime and replacement of a soft seated valve. Total cost of ownership may favor the metal seat. Understanding your process conditions is key to determining the right seat for your application.
Repairable components: Typically these include the ball, stem, body and end piece, and metallic parts with minor damage. That minor damage can be repaired by welding/machining or undercut/coating to rebuild them back to size. In most severe service design concepts, there is a straight-thru flow port.
How to Replace the Seat and Seal of the Electric Ball Valve? Disassembly Keep the valve in a half-open position to flush and remove dangerous substances that may exist inside and outside the valve. Close the ball valve, remove the connecting bolts and nuts on both flanges, and then completely remove the valve from the pipeline.
Designed to replace thru-conduit gate valves in mainline service. Ideal for manifolds, tank farms, pig launchers, river crossings, hot-taps or any other application where a positive, bubble-tight seal is required. The Dual-Seal Ball Valve is capable of acting as an emergency shut-down valve when used with a fail-close actuator.
Spears® True Union 3-way ball valves provide maximum versatility with fully interchangeable valve cartridges. This provides for easier system design modifications and upgrades in multiphase projects, or anywhere changes in valve types are desired. Simply exchange any True Union 2000 valve in-line using existing union nuts.

Linquip gathered around all the necessary information you need to know about ball …
Whereas, a gate valve and ball valve has two seats; one on the upstream side and the other on the downstream side. The valve leakage rate is directly proportional to the effectiveness of the seal between the valve disc and seat(s). Valve seats may be integral or replaceable rings. Valves are generally provided with screwed, welded, or ...
DESIGN. Enabled by a unique "C" ball shape and double eccentric design, the ²XC ball valve acts along two vectors of movement to allow opening and closing of the valve without friction or wearing at the seat and "C" contact. Sealing. At close, a zero leakage metal to metal seal is formed by cam effect, one full order of magnitude ...
If possible, fully cycle the valve so the ball is swept clean of debris. Ball valves are poor throttling valves because damage to the ball or seat will affect performance. Keep the valve fully open while in service. Don't use excessive torque while operating valve or damage will result. Open the Block & Bleed fitting on a closed
This will require the replacement of the washer to restore the valve's watertight integrity. Fortunately, the low cost of parts and the relative ease of repair makes faucets with compression valves a viable option for most homeowners. 2. Ball Valve. Another common type of valve found in faucets is the ball valve. Ball valves are used in single ...

Trunnion mounted ball valves with two unidirectional (self-relieving) seats are designed for blocking the fluid in both directions. Each seat is sealing in one direction, from the valve ends to the valve body cavity. The difference in area (D=A-B) times the line pressure creates a "piston effect" force which pushes the seat against the ball ...
