Series 530C

Calibrated Pressure Relief Valves

Features

• Calibrated adjustment feature for setting valve to relief pressure required

• Adjustable range 50 - 175 psi (3.45 - 12.06 bars)

• All bronze construction

• All stainless steel springs

• Buna-N disc on machined body seat

Specifications

• Sizes 1⁄2" and 3⁄4" (15 & 20mm)

• Inlet (bottom) male threaded, NPT

• Outlet (side), female threaded, NPT

Design

• The Watts Series 530C are spring operated bronze relief valves designed to be used only as protection from the build up of excessive pressure in systems containing water, oil or air.

• The Watts Series 530C are not ASME approved safety relief valves and should not be used in system applications with this requirement.

• Incorporate a calibrated adjustment feature for setting the valve to the relief pressure required.

Application

• Ideally suited for bypass thermal expansion pressure relief

• Not an ASME approved safety relief valve

Model 3L

ASME Rated, Design Certified and Listed by C.S.A.

Used for protection against excessive pressure on domestic storage tanks or tankless water heaters. Similar in construction to Watts Model 10L, the Model 3L has no temperature relieving element. Pressure range 75-150 psi (5.17-10.34 bars). Standard setting 75, 100, 125 and 150 psi (5.17, 6.90, 8.61 and 10.34 bars). Size 3⁄4" x 3⁄4" (20mm x 20mm). Popularly used in conjunction with the Model 210 gas shutoff valve on gas water heaters to shut off gas to heater if water heater temperature exceeds 210°F (99°C).

Solar - For solar applications Model 3L, specify Z9 for stainless steel lever and pin for outside solar applications.

Model 3L - has ASME construction and is tested, listed and certified by the National Board of Boiler and Pressure Vessel Inspectors.

ANSI Z21.22 “Relief Valves for Hot Water Supply Systems.”

Model 53L

Same basic design as Model 3L except it is furnished in 1⁄2" (15mm) size and does not comply with A.S.M.E. requirements.

• Bronze body and stainless steel spring. NOTE: On all the above pressure relief valves, pressure setting should be not less than 25-

30 psi above the maximum service main pressure.

Series BP30

Diaphragm Operated Relief Valve Bypass Control Valves

Diaphragm actuated bypass relief valves to regulate liquid pressure as supplied by a positive pressure pump. Protects equipment by opening at desired setting and allowing excess volume to be bypassed back to source. Construction is bronze body. Sensitive rubber diaphragm and special Teflon disc. Tee handle facilitates pressure change. Spring and adjustment handle free from contact with liquid elements being controlled. Max. temperature 180°F (82°C).

Pressure Ranges:

BP30A - Pressure range 10-50 psi (.7-3.45 bars) BP30B - Pressure range 45-100 psi (3.10-6.90 bars) BP30C - Pressure range 75-175 psi (5.17-12.06 bars)

Well System Relief Valve

Model 30L-Z1 - Well system relief valve. Capacity: 20 gpm at 10 psi over pressure (85 psi) Model 30L - with test lever; not diaphragm activated, for pressure relief service only. Nominal size:

(15mm), NPT male inlet x female (drain) outlet. Standard pressure setting 75 psi (5.17 bars). Optional settings 100, 125 and 150 psi (6.9, 8.6, 10.3 bars). These valves are not diaphragm actuated as needed for certain applications like bypass control service. For adjustable non-lever diaphragm actuated relief or control service, see BP30 Series.

Model N30 - Pressure range 5-25 psi (0.3-1.7 bars) and less lever. Model N30L - Pressure range 30-50 psi (2.07-3.45 bars). Standard setting 30 or 45 psi (2.07 or 3.10 bars).
