1. DESCRIPTION
The Viking Micromatic® Standard Response Pendent VK202 Sprinkler is a small,
thermosensitive, glass-bulb spray sprinkler available in several different finishes, temperature
ratings, and K-Factors to meet design requirements. The special Polyester and Electroless
Nickel PTFE (ENT) coatings can be used in decorative applications where colors are
desired. In addition, these coatings have been investigated for installation in corrosive
atmospheres and are listed/approved as corrosion resistant as indicated in the Approval
Charts.
Viking standard response sprinklers may be ordered and/or used as open sprinklers (glass bulb and
pip cap assembly removed) on deluge systems. Refer to Ordering Instructions.

3. TECHNICAL DATA
Specifications:
Minimum Operating Pressure: 7 psi (0.5 bar)†
Maximum Working Pressure: 175 psi (12 bar) wwp
Factory tested hydrostatically to 500 psi (34.5 bar)
Thread size: 1/2” NPT, 15 mm BSPT, 3/4” NPT, 20 mm BSPT
Nominal K-Factor: 8.0 U.S. (115.2 metric**)
Glass-bulb fluid temperature rated to -65 °F (-55 °C)
Overall Length: 2-1/4” (57 mm)
† cULus Listing, FM Approval, and NFPA 13 installs require a minimum of 7 psi (0.5 bar). The minimum operating pressure for CE Approvals ONLY
is 5 psi (0.35 bar).
** Metric K-factor measurement shown is in Bar. When pressure is measured in kPa, divide the metric K-factor shown by 10.0.
Material Standards:
Frame Casting: Brass UNS-C84400
Deflector: Phosphor Bronze UNS-C51000†† or Copper UNS-C19500
Bulb: Glass, nominal 5 mm diameter
Belleville Spring Sealing Assembly: Nickel Alloy, coated on both sides with PTFE Tape
Screw: Brass UNS-C36000
Pip Cap and Insert Assembly: Copper UNS-C11000 and Stainless Steel UNS-S30400
For Polyester Coated Sprinklers: Belleville Spring-Exposed
For ENT coated Sprinklers: Belleville Spring - Exposed, Screw and Pipcap - ENT plated.
††Not for FM Approval.
Ordering Information: Refer to Table 1.
4. INSTALLATION
Refer to appropriate NFPA Installation Standards.
5. OPERATION
During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the glass to shatter, releasing the pip cap and
sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern
to extinguish or control the fire.

Jurisdiction. Refer to specific installation standards.
3. UL Listed as corrosion resistant.
4. FM Approved corrosion resistant.
5. The corrosion resistant and corrosion proofing coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Chart(s).
These tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are compatible with or
suitable for the proposed environment. For automatic sprinklers, the coatings indicated are applied to the exposed exterior surfaces only. Note that the spring is exposed
on sprinklers with Polyester and ENT coatings. For ENT coated automatic sprinklers, the waterway is coated.
6. Sprinklers of Ultra-High temperature rating are intended for use inside ovens, dryers, or similar enclosures with normal operating temperatures above 300 °F (149 °C).
Where the ambient temperature around the Ultra-High temperature rated sprinkler is significantly reduced below 300 °F (149 °C), response time may be severely retarded
7. Wax melting point is 170 °F (76 °C) for 286 °F (141 °C) temperature rated sprinklers. For more inforamation regarding wax coatings, refer to Bulletin Form No. F_010201.
8. Allows use from the floor by attaching a length of 1” diameter CPVC tubing to the tool. Ideal for sprinkler cabinets. Refer to Bulletin F_051808.
