The Series 2300 Grazing Valve is used in the same applications as the Series 2000 Clover Valve. They differ in that the stem does not project above the cover. This feature reduces the chance of damage to the valve from livestock or other traffic. A brass tee handled key is required to open and close the valve.
All You Need to Know About Bellow Seal Globe Valve - Comparison of Bellows Seal Globe Valve with Normal Valves. Ø When valves with gland packing are used such as gate valves or ball valves in the system for heated oil transfers (permeability of heated oil is about 50 times that of steam), chances of hot oil spillage are quite high and can cause loss of equipment and property.

Ball Valve - an overview ScienceDirect TopicsThe design should ensure that the stem should not be capable of ejection from the valve while the valve is under pressure by the removal of the stem seal retainer, e.g., gland, alone. Body seat rings:Body seat rings or seat ring assemblies should be designed so as to be renewable except for those valves having a one=piece sealed (welded) body

the DSI® stem packing seal area for Gate and Globe Valves and in the bonnet gasket sealing area (cover gasket for Check Valves). In-house testing procedure has been devel-oped and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the DSI® Gate, Globe and Check Valve meeting
Gate valves - VelanVelan is a world leader in the design and production of a wide range of cast and forged steel gate, globe, check, ball, triple-offset butterfly, knife gate, highly engineered severe service valves, and steam traps offering superior performance across all major industrial applications.
Major Valve Parts - ASME Caesar II CalgaryThese parts include valve seat(s), disc, glands, spacers, guides, bushings, and internal springs. The valve body, bonnet, packing, et cetera that also come in contact with the flow medium are not considered valve trim. The gate-valve disc or wedge has two seating surfaces that come in contact with the valve seats to form a seal for stopping
The operation of resilient wedge gate valve is not like that of a double disc gate valve. Resilient wedge gate valves require considerable torque to fully shut off the flow through the valve but are easily opened. Closing torque to close the valve can be expected to be as follows:2 20 ft-lb 6 110 ft-lb
VALVE STEM PACKING REPLACEMENT METHOD VALVE STEM PACKING. The purpose of valve packing is to prevent leakage. In a typical valve, the gland follower is tightened until there is no leakage. The valve is then test-operated to make sure that the packing is not compressed so tightly that the valve does not turn easily.

A valve may have multiple seats. In the case of a globe valve and swing-check valve, there is one seat. 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).
