2 ulletin 71.1:95 Introduction The 95 Series regulators are compact, large-capacity, direct-operated pressure regulators (see Figures 1 and 2). The units are available in NPS 1/4 through 2 (DN 15 through 50) sizes and is offered in several different end connection configurations. They are designed to handle pressures up to 600 psig (41,4 bar) and temperatures up to 650 F (343 ). This product can help solve the toughest pressure control applications. Typical applications include superheated steam, steam injection, steam tracing, nitrogen purging, boiler feed water, process chemicals, cooling water, test fixtures, wash tanks, sterilizers/ autoclaves, fuel lines, pneumatic supply, and many others.

5 outlet pressure, psig E / IL Figure 3. ir Flow Performance urves of a NPS 1 (DN 25) Type 95L Regulator Principle of Operation The 95 Series (refer to Figure 2) is a direct-operated regulator. Downstream pressure is registered internally through the body to the under side of the diaphragm. When the downstream pressure is at or above the set pressure, the disk is held against the orifice, and there is no flow through the regulator. When demand increases, downstream pressure drops slightly allowing the spring to extend, moving the stem down and the disk away from the orifice. This allows flow through the body to the downstream system. Types 95H, 95L, 95HP, and 95HT use spring force to regulate outlet pressure. Types 95HD and 95LD use spring force to maintain a differential pressure between spring case loading pressure and outlet pressure. Installation The 95 Series regulators may be installed in any position, as long as flow will be in the same direction as that indicated by the body arrow. The Types 95H, 95L, 95HT, and 95HP regulators should be installed so that their spring case vents are protected from anything that might clog them. air flow in Nm 3 /h air flow in thousands of SFH ulletin 71.1:95 53, psig (1,7 bar) at inlet 50 psig (3,5 bar) at inlet initial setpoint = 15 psig (1,0 bar) at 300 SFH (8,0 Nm 3 /h) flow rate with 100 psig (6,9 bar) at inlet capacity at 10% droop capacity at 20% droop 200 psig (13,8 bar) at inlet 100 psig (6,9 bar) at inlet Emerson provides an instruction manual with every regulator shipped.

For example, refer to the air flow rate curve in Figure 3. The regulator is set for 15 psig (1,0 bar) at the outlet, with 100 psig (6,9 bar) at the inlet and a 300 SFH (8,0 Nm 3 /h) flow rate. apacity at 10% droop is read at the intersection of a line projected horizontally to the right from the 13.5 psig (0,93 bar) outlet pressure point and the 100 psig (6,9 bar) inlet curve. The 13.5 psig (0,93 bar) is derived by applying the droop factor of 10% to the regulator setting of 15 psig (1,0 bar). The same method is employed for 20% droop, except the capacity value is read at the 12 psig (0,83 bar) outlet pressure point, 20% less than the 15 psig (1,0 bar) setting. For highest capacity and the most accurate control within a particular type of the 95 Series regulators, use the lowest range spring that can be adjusted to the desired setpoint (see Table 5 for part numbers of appropriate springs for each body size).

If closer control is necessary, a regulator of larger capacity or different design should be selected, so that the necessary flow can be obtained with a smaller droop factor. Sometimes it may be necessary to interpolate the capacity table data to determine capacity for outlet settings not given. To maintain accuracy, it is important when interpolating to stay within a spring range if possible. The following is a procedure for interpolating the data to calculate flow: 1. Determine which spring is to be used. 2. Find the two outlet settings (P 2 a and P 2 b) that bracket the actual outlet pressure P For a given body size and inlet pressure, find the capacity Qa for P 2 a and Qb for P 2 b. 4. Use the following formula to determine the interpolated capacity (Q). Qb - Qa Qb - Q = P 2 b - P 2 a P 2 b - P 2 OSOLETE DOUMENT

Solution: Qa = 1100 SFH (29,5 Nm 3 /h) P 2 a = 15 psig (1,0 bar) Qb = 1600 SFH (42,9 Nm 3 /h) P 2 b = 30 psig (2,1 bar) Q = 1270 SFH Q = 34,0 Nm 3 /h Q = ,9-29,5 42,9 - Q = 2,1-1,0 2,1-1,4 Note The same interpolation procedure can be used for different inlet pressures. n alternative method for interpolating capacities is to back calculate v s as shown in Table 2. ontact your local Sales Office if you should have any questions about selecting the proper regulator. ir apacities Regulating capacities at selected pressures and outlet pressure flows are given in SFH (60 F and 14.7 psia) of air. To determine the equivalent capacities for other gases, multiply the table capacities by the following appropriate conversion factors: 1.29 for 0.6 specific gravity natural gas, for propane, for butane, or for nitrogen. For gases of other specific gravities, divide by the square root of the appropriate specific gravity. Then, if capacity is desired in Nm 3 /h at 0 and 1,10325 bar, multiply SFH by apacities in Tables 8, 9, 10, and 11 are for regulators using elastomer diaphragms. Depending on regulator construction, a multiplier must be used to convert to capacities for regulators using metal diaphragms. ulletin 71.1:95 To determine wide-open flow capacity for relief valve sizing of air at a temperature of 60 F, use the equation for critical pressure drops (absolute outlet pressure equal to one-half or less than one-half the absolute inlet pressure). Q = P 1(abs) g where, Q = Gas flow, SFH (60 F and 14.7 psia) P 1(abs) = bsolute inlet pressure, psia (add 14.7 psi to gauge inlet pressure to obtain absolute inlet pressure) g = Wide-open gas sizing coefficient from Table 4 For pressure drops lower than critical (absolute outlet pressure greater than one-half the absolute inlet pressure), use the sizing nomographs in Fisher atalog 10, or the Fisher Sizing Program. To obtain capacities in Nm 3 /h at 0 and 1,01325 bar, multiply the capacity determined in SFH by Steam apacities apacities in Tables 13, 14, 15, 16, and 17 are in pounds/h of saturated steam. To obtain capacities in kg/h, multiply the capacities given in the table by apacities have been calculated for stainless steel diaphragms only since steam service exceeds the elastomer diaphragm temperature limits. To determine wide-open flow capacity for relief valve sizing of steam, use the equation for critical pressure drops (absolute outlet pressure equal to one-half or less than one-half absolute inlet pressure). Q = P 1(abs) s where, Q = Steam flow, pounds/h P 1(abs) = bsolute inlet pressure, psia (add 14.7 psi to gauge inlet pressure to obtain absolute inlet pressure) s = Wide-open steam sizing coefficient from Table 4 For pressure drops lower than critical (absolute outlet pressure greater than one-half absolute inlet pressure), use the sizing nomographs in Fisher atalog 10, or the Fisher Sizing Program.
