1 Newman-Milliken ubricated Parallel Plug Valves Cast Iron

2 The principle of the Newman-Milliken valve is as simple as its design... The plug, which is the only moving part in the valve, when open presents a straight through passage inline with the pipe-line, and when turned through 90 degrees to the closed position stops the flow. A special sealing compound is used to effect a completely leak tight seal. When line pressure is applied to the valve in the closed position, the parallel plug is forced to the downstream side of the valve. The plug is then in contact with the body in the area surrounding the outlet port in the body. The sealing compound which surrounds the outlet port by means of special grooves in the plug, forms a barrier to line pressure and is also spread over the sealing surfaces of the plug and body so that a very thin film of compound is established between the plug and body surfaces on the downstream side. The metal-to-metal contact of plug and body together with the barrier of sealing compound ensures a completely leak tight valve. The sealing compound also preserves the body and plug surfaces from corrosion and to some extent, abrasion, and provides lubrication for ease of operation. Providing the valve is correctly maintained, which simply means injecting a small amount of sealing compound from time to time and moving the plug, positive shut-off will result and provide many years of satisfactory service. CAN/CA 3.11 Newman-Milliken Plug Valves 170M/171M 200M/201M are CA Approved (1/2 8 ) earing earboxes can be fitted to valves. In the catalogue, we indicate where we consider this necessary as standard.

3 About This Catalogue The Illustrations shown are representative of certain sizes of each line of valve, but do not necessarily represent all sizes in all details. Weights shown are approximate and not guaranteed. They represent the average weight of product at the time information was compiled. The ubricated Plug valves shown in this publication meet or exceed the testing specification of MSS-SP78 and S All ratings represent the maximum allowable Non-Shock pressure at the indicated temperature. The operating temperature of the valve is taken to be the temperature of the medium flowing through it. The temperature must not exceed the temperature shown on page 2. We reserve the right to make changes in materials, designs, dimensions and specifications without notice. All purchases are subject to Newman Hattersley Canada td. Terms and Conditions of Sale.

4 Pressure / Temperature Ratings Note: The pressure/temperature ratings given apply to the valve only. The maximum temperature at which a valve may operate depends upon the sealing compound with which the valve is filled. However, should the sealing compound have a higher temperature than the temperature given in the pressure/temperature ratings then the lower temperature must apply.

5 Servicing Instructions Positive Isolation with Minimum Maintenance Sealing In service sealing compound should be used for each individual medium to affect good isolation. Our recommendations for sealing compounds are the result of considerable research. If there is any doubt as to the suitability of a particular compound for a given service, tests should be carried out in a new clean valve. This is the only way to conduct such tests. aboratory tests using a beaker of line fluid and immersing a stick of compound have proved misleading. Where samples of fluid can be supplied, together with details of temperature and pressure, and if known frequency of operation, we will carry out specific tests and give our recommendations based upon the results. Construction Only five major parts are involved when dismantling: i.e. body, parallel plug, PT thrust ring, bottom cover and plug support spring. Operation Care must be taken particularly with geared valves that the plug is eased off the body stop after operation to ensure the plug is free to float. Routine Maintenance Valves are dispatched by Hattersley charged with sealing compound. A compound identification tag states clearly that the valve has been assembled and tested with a universal compound. The user is advised to follow the chart overleaf for specific applications. When injecting additional sealing compound, care should be taken to ensure that it is of the correct type. Where the service permits, the valve should be partially or fully operated once to ensure free operation and to determine the effort required. or infrequently operated valves maintenance merely consists of two or three turns of the combination screw or, if gun injection, several strokes of the lever, and opening and closing the valve a minimum of three times to distribute the compound evenly around the plug at three monthly intervals. It is difficult to specify how often the valve should be recharged with sealing compound, since this is determined by the frequency of operation, type of service, pressure and temperature. Injection of Compound When the combination screw has reached its limit (screwed fully down), this indicates that the valve needs re-charging with sealing compound. When using sticks or the lightweight compound gun, remove the combination screw, insert a stick or partially fill the compound reservoir in the plug, replace the combination screw, and screw down. This operation may need repeating several times. When using the NM 40 high-pressure gun, attach the nozzle to the injection nipple and give several steady strokes of the lever. VAVS MUST ITHR UY OPN OR UY COSD WHI THY AR IN CHARD. Indication of ull Charging The first indication of the valve becoming fully charged is an increase in the effort required to rotate the combination screw, or with the high pressure gun injection an increase in the effort required on the lever. The effort required to operate the valve should have increased from the initial operation prior to injection of sealing compound. Method of Injection Where the number of valves to be charged is small, i.e valves, especially if they are in the smaller sizes, stick or lightweight gun injection can be successfully used. or larger quantities use of the NM 40 high pressure gun is recommended. Valve eakage eakage through the valve indicates that the valve requires injection of sealing compound or that it needs opening and closing a minimum of three times to distribute the compound evenly. Operating Torque Should a valve become jammed or unusually stiff to operate, this can generally be cured by the injection of sealing compound. If this is ineffective, it will be necessary to dismantle the valve, clean the components and recharge with sealing compound.

The body has 2 small recesses cast in it which connect the low pressure grooves to the 2 peripheral grooves. Compound is injected into the plug. The compound passes through a small ball check valve... into a horizontal cross hole and into the top peripheral groove. rom here it is forced down the high pressure grooves... and into the bottom peripheral groove... with the plug fully open or fully closed the compound enters the top body recess. Through the low pressure grooves and into the bottom body recess... with the valve partly open the body recesses do no connect with the low pressure grooves. 4
