INTRODUCTION
The HC K4 series of dependable, com pac t, rugge d
in-line check valve s (disc type n on- return va lves) is
ideally suited for refr igerant flow control applications.
Valves open wide for flow in the arrow direction on the
valve bo dy. Valves close quickly a nd r eli abl y when
flow r eversals occur.
Plated b odies a nd st ainless steel sea t discs a nd
spring s enable them to withstand expec ted indus trial
refriger ation conditi ons. Fur t her mor e, these check
valves can be mounte d in any position and close-
coupled to other valves .
ADVANTAGES
These compa ct c hec k valves offer reliable op eratio n
regar dless of posit ion. Corrosion resistant stainl ess
steel seat disc. Metal-to-metal seats facilitate durable,
tight clo sing of valves .
APPLICATIONS
These i n-line c hec k valve s are designed to p rovide
refriger ant flow control to hot gas lines, liquid li nes ,
compressor discharg e line s, suction lines , an d hot
ga s heate d drain pans.
Th ese valves are n ot rec omm ende d for use with
pu l s a ting l oads s uch a s low speed c ompressor
discharge and screw compressor side port applications.
For applications suc h as the se, use Han sen HCK1
piston type check valves.

INSTALLATION DIMENSIONS
INSTALLATION
Val ve may be loc ated in any position. Arrow on valve
body should match direction of flow. Se cur e valve
with gaskets between flanges and tighten bolts evenly.
Do not use this valve or any component to alig n pipes
or tighten gap b etween f lan ges .
Do not install on inlet side of solenoid valves or control
valves with electric shut-off or shut-of f valves unless
a relief valve is used from therein between piping. Do
not insta ll on inl et side of outlet pressure regulators
where l iquid may become tra ppe d. In stead, c hec k
valves should be located on outlet side of these valves.
Check valves can be close- coupled to other matching
solenoi d va lves, p res sur e reg ulato rs, o r str ainers by
using a Male Adapter Ring a nd longer bolts supplied
when so specified on orde r. For pr oper flange gasket
sealing, care must be taken when threading or welding
to assure fl ang es are p arallel to each ot her and
perpendicular to pipe. Also, gaskets should be lightly
oile d and all bolts m ust be tig htened evenl y.
